                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%,
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Prior to 9/1/98 (for Class C
shares) and 1/2/04 (for Class I shares), performance for Class C and Class I
shares includes the historical performance of Class B shares adjusted to reflect
the applicable sales charge (or CDSC), fees, estimated expenses, and fee
waivers/expense limitations of Class C and Class I shares upon initial offer.
Unadjusted, the performance shown for the newer classes of shares might have
been lower.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CAPITAL APPRECIATION FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Edmund C. Spelman of MacKay Shields LLC

HOW DID MAINSTAY CAPITAL APPRECIATION FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Capital Appreciation Fund returned 19.29%
for Class A shares, 18.41% for Class B shares and 18.45% for Class C shares for
the 12 months ended October 31, 2007. Over the same period, the Fund's Class I
shares returned 20.01%. All share classes underperformed the 21.72% return of
the average Lipper(1) large-cap growth fund for the 12-month reporting period.
Class A and Class I shares outperformed--and Class B and Class C shares
underperformed--the 19.23% return of the Russell 1000(R) Growth Index,(2) the
Fund's broad-based securities-market index, for the 12 months ended October 31,
2007. See page 5 for Fund returns with sales charges.

DURING THE REPORTING PERIOD, WHICH SECTORS HAD THE GREATEST POSITIVE IMPACT ON
THE FUND'S PERFORMANCE, AND WHICH HAD A NEGATIVE IMPACT?

Sector weightings in the Fund result from our bottom-up, stock-by-stock
selection process. During the reporting period, the Fund's top-performing
sectors in terms of absolute and relative returns were technology, energy and
materials. Consumer and retail stocks experienced the biggest absolute declines.

WHICH INDIVIDUAL SECURITIES WERE THE STRONGEST PERFORMERS DURING THE REPORTING
PERIOD?

Top-contributing stocks during the reporting period included Southern Copper,
which produces copper and operates mining, smelting and refining facilities;
National Oilwell Varco, an exploration and production services and equipment
company, which experienced increased demand largely because of rising oil
prices; and Apple Computer, which benefited from continued strong sales for its
existing products and from the company's entry into the cellular phone handset
market.

DURING THE REPORTING PERIOD, WHICH STOCKS DETRACTED FROM PERFORMANCE?

Holdings in financial services and retail detracted from the Fund's performance.
First Marblehead, which provides services for private education loans, saw its
share price decline on investor concerns about the credit markets and new
entrants into the field of education loans. Merrill Lynch shares declined
because of the company's exposure to collateralized debt obligations and
mortgage-backed securities. J.C. Penney's shares fell on weaker-than-expected
sales and because of investor concerns about consumer spending.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

In light of their strong contributions to performance, Southern Copper and
National Oilwell Varco were the Fund's most significant new positions. The Fund
also initiated positions in ExxonMobil and Google during the reporting period.

We eliminated the Fund's positions in a number of industrial stocks, such as
Danaher, which designs and manufactures industrial and consumer products;
Federal Express, a worldwide express delivery company; and United Technologies,
which provides high-technology products and support services to customers in the
aerospace and building industries worldwide. We also eliminated some of the
Fund's retail holdings, including Lowe's. The company sells goods and services
for home improvement.

HOW DID THE FUND'S WEIGHTINGS AFFECT PERFORMANCE DURING THE REPORTING PERIOD?

During the reporting period, the Fund remained significantly overweight relative
to the Russell 1000(R) Growth Index in energy and modestly overweight in
materials. Both of these positions contributed positively to the Fund's
performance. Stock selection in the underweight health care sector also
contributed positively to the Fund's results relative to the benchmark. On the
other hand, a meaningful overweight in the consumer discretionary sector
detracted from the Fund's performance.


The principal risk of growth stocks is that investors expect growth companies to
increase their earnings at a certain rate that is generally higher than the rate
expected for nongrowth companies. If these expectations are not met, the market
price for the stock may decline significantly, even if earnings showed an
absolute increase.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Capital
Appreciation Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. Class I shares commenced on January 2, 2004.
Class A shares are offered at net asset value per share plus an initial sales
charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within up to six years of purchase of Class B
shares and a 1% contingent deferred sales charge may be imposed on redemptions
made within one year of purchase of Class C shares. Class I shares are not
subject to a sales charge. As approved by the Board of Trustees in 1997, Class B
shares convert to Class A shares eight years after the date they were purchased.
The four classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A shares under a distribution plan pursuant to Rule 12b-1 under
the 1940 Act. Class I shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek long-term growth of capital. Dividend
income, if any, is an incidental consideration.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Investments
in mutual funds are valued at their net asset value as of the close of the New
York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

 18   MainStay Capital Appreciation Fund


(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 20) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Trust, on behalf of the Fund, pays NYLIM a monthly fee for services
performed and the facilities furnished at an annual percentage rate of the
Fund's average daily net assets as follows: 0.72% on assets up to $200 million,
0.65% on assets from $200 million to $500 million and 0.50% on assets in excess
of $500 million. For the year ended October 31, 2007, NYLIM earned fees from the
Fund in the amount of $6,179,731.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 9 on page
22.)

                                                    www.mainstayfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $120,946. Additional payments
were made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $71,455 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $9,716, $499,477 and $1,014, respectively, for the year ended October
31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $3,575,389.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>

</Table>

* Less than one-tenth of a percent.

(H) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $39,393.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $132,461 for the year ended
October 31, 2007.

NOTE 9--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the MainStay
Capital Appreciation Fund was $3,205,000. NYLIM has reimbursed or paid all
expenses relating to the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes", an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Capital Appreciation Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year period
then ended, and the financial highlights for each of the years or periods in the
four-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Capital Appreciation Fund of The MainStay Funds as of October 31, 2007,
the results of its operations for the year then ended, the changes in its net
assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years or periods in the four-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF
MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's underperformance over
various time periods reviewed.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate,
and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints that would reduce the Fund's management fee at levels
above the breakpoints, and the fact that the breakpoints were intended to
provide that shareholders

 24   MainStay Capital Appreciation Fund


would share in benefits from economies of scale obtained through the growth in
the Fund's assets. The Trustees noted that the Fund's management fee rate had
been reduced by the breakpoint schedule applicable to the Fund, although they
also noted that the Fund's asset size had decreased over the past several years.
The Trustees reviewed information about the potential effect of asset growth on
Fund expenses, the difficulty of forecasting its effect on the profitability of
the Manager and its affiliates, and the management fee breakpoints applicable to
the Fund and certain other funds.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager including other registered funds and separate
institutional accounts having investment strategies similar to that of the Fund,
and took account of explanations and other information relating to the fees and
expenses of those other funds and accounts. The Trustees considered the current
and proposed contractual and net management fees, its anticipated gross and net
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationships among the Manager, the Subadvisor and the Trust and the
likely difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Performance figures reflect
certain fee waivers and/or expense limitations, without which total returns may
have been lower. These fee waivers and/or expense limitations are contractual
and may be modified

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY COMMON STOCK FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Harvey Fram, CFA, of New York Life
Investment Management LLC

HOW DID MAINSTAY COMMON STOCK FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Common Stock Fund returned 12.24% for
Class A shares, 11.39% for Class B shares and 11.47% for Class C shares for the
12 months ended October 31, 2007. Over the same period, the Fund's Class I
shares returned 13.03%. All share classes underperformed the 14.56% return of
the average Lipper(1) large-cap core fund and the 14.56% return of the S&P
500(R) Index,(2) for the 12-months ended October 31, 2007. The S&P 500(R) Index
is the Fund's broad-based securities-market index. See page 5 for Fund returns
with sales charges.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S PERFORMANCE AND WHICH SECTORS WERE WEAK?

The sectors that made the greatest positive contri-butions to the Fund's
performance relative to the S&P 500(R) Index were financials, materials and
energy. The Fund generally had underweight positions in the financial stocks
that had the greatest exposure to the mortgage crisis, such as Countrywide
Financial. The Fund enjoyed overweight positions in materials stocks that
benefitted from rising commodity prices. Significant exposure to energy stocks
also helped performance when the price of oil climbed to new highs.

Information technology, consumer discretionary and health care were the Fund's
weakest-performing sectors relative to the S&P 500(R) Index. The Fund maintained
an overweight position in information technology, which was one of the
best-performing sectors during the reporting period. Unfortunately, underweight
positions in strong performers such as Apple and Google detracted from the
Fund's relative results. An overweight position in the consumer discretionary
sector hurt performance when many of the Fund's holdings were adversely affected
by a slowdown in construction and by difficulties in the subprime mortgage
market. In the health care sector, significant exposure to a number of managed
health care stocks, including UnitedHealth Group, hurt performance.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S
PERFORMANCE DURING THE REPORTING PERIOD?

The three strongest individual contributors to the Fund's performance during the
reporting period were Freeport-McMoRan, National Oilwell Varco and Cummins.
Freeport-McMoRan, a copper and gold mining company, benefited from the rising
price of copper. National Oilwell Varco, an oil & gas equipment & services
company, performed well, as the rising price of oil caused demand for the
company's products to soar. Cummins, a manufacturer of engines and related
technologies, saw its stock price rise as its clean diesel technology catapulted
the company into a leadership position in its industry.

WHICH INDIVIDUAL STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE
REPORTING PERIOD?

Major detractors from the Fund's performance during the reporting period were
Circuit City Stores and Lennar. Both companies were affected by the slowdown in
consumer spending. A sizable position in Merrill Lynch also hurt the Fund's
performance when it became clear that the company faced large losses on its
subprime mortgage exposure.

WHAT WERE SOME OF THE FUND'S PURCHASES AND SALES DURING THE REPORTING PERIOD?

The Fund seeks stocks with attractive valuations, reliable earnings and strong
price trends. Among the stocks purchased by the Fund during the reporting period
were Microsoft and EMC. Both of these stocks appeared reasonably valued, and
both were benefiting from continued strength in technology spending. Securities
that were sold during the reporting period included Kohl's and Regions
Financial. We sold Regions Financial to reduce the Fund's exposure to
financials, and we sold Kohl's to reduce exposure to the U.S. consumer.

DID THE FUND HAVE ANY SIGNIFICANT UNDERWEIGHT OR OVERWEIGHT POSITIONS AT THE END
OF THE REPORTING PERIOD?

Weighting changes in the Fund result from a combination of security performance
and the Fund's proprietary quantitative security-selection process.


The principal risk of growth stocks is that investors expect growth companies to
increase their earnings at a certain rate that is generally higher than the rate
expected for nongrowth companies. If these expectations are not met, the market
price of the stock may decline significantly, even if earnings showed an
absolute increase. The Fund may experience a portfolio turnover rate of more
than 100% and may generate taxable short-term capital gains.

During the reporting period, the Fund's weightings in the financials and
consumer discretionary sectors decreased. The Fund's weightings in energy and
industrials increased.

As of October 31, 2007, the Fund was overweight relative to the S&P 500(R) Index
in Northern Trust, a bank that appeared to have little exposure to subprime
mortgages, and McKesson, a health care distributor that has benefited from the
move to keep health costs down.

At the end of October 2007, the Fund held underweight positions in Target, which
had been hurt by a slowdown in consumer spending, and in Comcast, which suffered
from competitive pressures. Despite continued strong performance, Apple and
Google were also underweight at the end of the reporting period because our
proprietary model found them expensive.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Common
Stock Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares and Class B
shares commenced on June 1, 1998. Class C shares commenced on September 1, 1998.
Class I shares commenced on December 28, 2004. Class A shares are offered at net
asset value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within up to six years of purchase of Class B shares and a 1% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are not subject to a sales charge. As
approved by the Board of Trustees in 1997, Class B shares convert to Class A
shares eight years after the date they were purchased. The four classes of
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that Class B and
Class C shares are subject to higher distribution fee rates than Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek long-term growth of capital, with
income as a secondary consideration.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Investments
in mutual funds are valued at their net asset value as of the close of the New
York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Board of Trustees to represent fair value.
Equity and non-equity securities which may be valued in this manner include, but
are not limited to: a security the trading for which has been halted or
suspended; a debt security that has recently gone into default and for which
there is not current market quotation; a security of an issuer that has entered
into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007 the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security transac-

 22   MainStay Common Stock Fund


tions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 24) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("NYLIM" or "Manager") a
registered investment adviser and an indirect wholly-owned subsidiary of New
York Life Insurance Company ("New York Life"), serves as the Fund's Manager.
NYLIM provides offices and conducts clerical, recordkeeping and bookkeeping
services, and is responsible for the financial and accounting records required
to be maintained by the Fund. NYLIM also pays the salaries and expenses of all
personnel affiliated with the Fund and all the operational expenses that are not
the responsibility of the Fund. The Fund is advised by the Manager directly,
without a Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.70% on assets up to $500 million and 0.65% on assets in
excess of $500 million, which is not recoupable. NYLIM has also contractually
agreed to waive a portion of its management fee so that the management fee is
0.60% on assets up to $500 million and 0.55% on assets in excess of $500
million, which is not recoupable. This fee may not be recouped by NYLIM.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.30%; Class B, 2.05%; Class C, 2.05%; and Class I, 0.62%.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. NYLIM may recoup the amount of any management fee waivers
or expense reimbursements from the Fund pursuant to the agreement if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which NYLIM incurred the
expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $1,833,057 and waived/reimbursed its fees in the amount of $609,922 of
which $348,057 is recoupable.

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
         OCTOBER 31,
  2008*      2009      2010      TOTAL
                      
 $124,534  $550,657  $348,057  $1,023,248
 ----------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.30% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $13,792 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $862, $42,036 and $1,198, respectively, for the year ended October 31,
2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $423,778.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>
                                                  
Class A                                        $  321     0.0*%

- -------------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(G) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $9,999.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $52,853 for the year ended
October 31, 2007.

NOTE 9--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
that fund's shareholders. Discussions have been held with the SEC concerning a
possible resolution of this matter. There can be no assurance at this time as to
the outcome of these efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes", an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

NOTE 11--SUBSEQUENT EVENT:

At a meeting held on June 6, 2007, the Board of Trustees approved a plan of
reorganization where the Fund would acquire the assets, including the
investments, and assume the identified liabilities of McMorgan Equity Investment
Fund, a series of the McMorgan Trust.

Shareholders of McMorgan Equity Investment Fund approved this reorganization on
November 20, 2007. The reorganization was completed on November 27, 2007. The
aggregate net assets of the Fund immediately before the acquisition were
$286,164,279 and the combined net assets after the acquisition was $485,490,761.

The acquisition was accomplished by a tax-free exchange of the following:

In exchange for the McMorgan Equity Investment Fund shares and net assets, the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Common Stock Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Common Stock Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years or periods in the four-year period then ended,
in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS.

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") (the
"Agreement") at a meeting held on May 22 and 23, 2007. In connection with the
approval of the Agreement, the Trustees reviewed a significant amount of a wide
variety of information that they had requested and received from the Manager,
and data and analysis from an outside data provider and a third party
consultant. The Trustees considered various industry trends and regulatory
developments in their deliberations. In considering approval of the Agreement,
and in evaluating the fairness of the compensation to be paid by the Fund, the
Trustees met both as a full Board and in executive session with no Interested
Trustee present, in advance of the meeting at which the Agreement was approved,
and they considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager. The Trustees reviewed the services that the Manager has
provided historically to the Fund, and also generally to other series of the
Trust. Among other services, the Manager's services have included investment
management services--which include, but are not limited to, monitoring and
evaluating the Fund's investment program and investment results, providing the
day-to-day portfolio management of the Fund, determining the composition of
assets of the Fund and the timing of the Fund's execution of the purchase and
sale of assets, and the Fund's compliance with its investment policies and
restrictions--and administrative services, including working with other service
providers of the Trust, maintaining certain Fund records, providing office
space, performing clerical and bookkeeping services for the Fund, preparing
Board materials and Fund filings, and otherwise managing the Trust's operations.
The Trustees considered, among other things, the Manager's management,
personnel, resources, operations and portfolio management capabilities. The
Board reviewed reports on the Manager's brokerage practices, including with
respect to best execution of portfolio trades. The Trustees considered the
Manager's supervision of the Fund's service providers and its attention to the
compliance program of the Trust, the Manager, and certain other service
providers. The Trustees noted the generally favorable results of a third party
review of the services and communications that NYLIM Service Company LLC, an
affiliate of the Manager, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, investment performance that was
better than the peer median over the several time periods considered, and
measures that the Manager had previously taken in seeking to improve the Fund's
performance by increasing the Fund's tracking error with respect to its
benchmark.

The Trustees considered the cost to the Manager of the Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods.

In reviewing profitability information, the Trustees reviewed, among other
things, information about the allocation of expenses among the Manager and its
affiliates. The Trustees were provided information that indicated that the
profitability to the Manager and its affiliates from the Management Agreement
with respect to the Fund was moderate, and from the overall relationship with
the Trust was low. The Trustees considered other benefits that the Manager and
its affiliates receive from the relationship with the Trust, including benefits
that NYLIFE Distributors and MainStay Shareholder Services receive in exchange
for services they provide to the Funds, and certain benefits from soft dollar
arrangements. The Trustees acknowledged certain benefits to the reputation of
the Manager and the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at levels
above the breakpoint, and the fact that the

 28   MainStay Common Stock Fund


breakpoint was intended to provide that shareholders would share in benefits
from economies of scale obtained through the growth in the Fund's assets. The
Trustees noted that the Fund not reached the asset level at which the breakpoint
would reduce the Fund's management fee rate. The Trustees reviewed information
about the potential effect of asset growth on Fund expenses, the difficulty of
forecasting its effect on the profitability of the Manager and its affiliates,
and the management fee breakpoints applicable to the Fund and certain other
funds.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager, including registered and other funds as well as
separate institutional accounts having investment strategies similar to that of
the Fund, and took account of explanations and other information relating to the
fees and expenses of those other funds and accounts. The Trustees considered the
current and proposed contractual and net management fees, its anticipated
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationship between the Manager and the Trust and the likely
difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager. The Trustees took account of the
Manager's willingness to maintain the management fee waiver and expense
limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreement. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering the Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of the Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of the Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $4,214,708.

The dividends paid by the Fund during the fiscal year ended October 31, 2007,
should be multiplied by 34.7% to arrive at the amount eligible for qualified
dividend income and 37.0% for the corporate dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will
be the amounts you are to use on your federal income tax return and will differ
from the amounts which we must report for the Fund's fiscal year ended October
31, 2007.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CONVERTIBLE FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES

The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Edward Silverstein, CFA of MacKay
Shields LLC

HOW DID MAINSTAY CONVERTIBLE FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Convertible Fund returned 20.10% for Class
A shares, 19.25% for Class B shares and 19.27% for Class C shares for the 12
months ended October 31, 2007. All share classes outperformed the 15.11% return
of the average Lipper(1) convertible securities fund and the 12.72% return of
the Merrill Lynch All Convertible Securities Index,(2) for the 12 months ended
October 31, 2007. The Merrill Lynch All Convertible Securities Index is the
Fund's broad-based securities-market index. See page 5 for Fund returns with
sales charges.

WHICH INDUSTRIES WERE STRONG PERFORMERS AND WHICH ONES WERE WEAK DURING THE
REPORTING PERIOD?

The best-performing industries for the Fund in absolute terms were oil services,
metals & mining and technology. Industries that detracted the most from absolute
performance included financial services, health care and retail.

WHICH INDIVIDUAL FUND HOLDINGS WERE THE STRONGEST PERFORMERS DURING THE
REPORTING PERIOD?

A convertible bond position in Cameron International was the Fund's strongest
holding during the reporting period. Cameron manufactures equipment used in oil
and gas development projects and has benefited from high energy prices. A
convertible bond position in oil & gas services company Schlumberger was the
Fund's second-best performer during the reporting period. Around the world,
nations and companies are intensively pursuing new reserves and new ways to
exploit existing ones. This trend has helped sales and earnings at both Cameron
International and Schlumberger.

Other strong performers included Vale Capital and metals & mining company
Freeport-McMoRan Copper & Gold. In the technology sector, EMC shares and
convertible bonds rose sharply, and the common stock of Microsoft enhanced Fund
performance.

WHICH OF THE FUND'S HOLDINGS WERE WEAK PERFORMERS DURING THE REPORTING PERIOD?

The Fund's position in the convertible bonds of Whole Foods Market showed poor
performance after the company reported that same-store sales growth was slowing.
The Fund's shares and convertible bonds of Merrill Lynch and KKR Financial
detracted from performance because of setbacks in the companies' subprime
mortgage holdings.

Synthetic convertible bonds of Boston Scientific suffered from a slowdown in a
key implantable cardiac-device franchise. Amgen's common stock and convertible
bonds fell when studies raised doubts about a key cancer drug.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

We initiated a position in convertible preferred shares of Vale Capital. The
shares appeared inexpensive relative to the company's current earnings and cash
flow, particularly in light of growing global demand for metal ores. We also
purchased the convertible bonds of General Cable on the premise that the
company's sales and earnings may increase substantially as utility companies in
the United States are forced to upgrade aging transmission and distribution
networks.

We sold the Fund's position in the convertible bonds of telecommunications
company NII Holdings after we sensed that increasing competition might slow the
company's growth in Mexico. We sold the Fund's convertible bonds of EDO after
the company received a takeover offer from ITT.

WERE THERE ANY CHANGES IN THE FUND'S WEIGHTINGS DURING THE REPORTING PERIOD?

Yes, there were several changes across various industry groups. We reduced the
Fund's energy weighting to lock in profits. The move also helped lower risk by
preventing a single sector from constituting more than 25% of Fund assets. We
also reduced the Fund's exposure to industrials with the sale of Wesco
convertible bonds. The Fund's consumer discretionary weighting increased
slightly


Issuers of convertible securities may not be as financially strong as issuers of
securities with higher credit ratings and may be more vulnerable to changes in
the economy. If an issuer stops making interest payments, principal payments or
both on its convertible securities, these securities may become worthless and
the Fund could lose its entire investment in them. High-yield securities ("junk
bonds") are generally considered speculative because they present a greater risk
of loss than higher-quality debt securities and may be subject to greater price
volatility. Foreign securities may be subject to greater risks than U.S.
investments, including currency fluctuations, less-liquid trading markets,
greater price volatility, political and economic instability, less publicly
available information, and changes in tax or currency laws or monetary policy.
These risks are likely to be greater in emerging markets than in developed
markets. The Fund may experience a portfolio turnover rate of more than 100% and
may generate taxable short-term capital gains.

when we added to an existing position in General Motors' convertible preferred
shares. The Fund's technology weighting increased modestly with the purchase of
Sybase convertible bonds and the market appreciation in our position in EMC.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2007, the Fund was significantly overweight relative to the
Merrill Lynch All Convertible Securities Index in the energy sector and slightly
overweight in health care. On the same date, the Fund was underweight relative
to its benchmark in financials and utilities.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay
Convertible Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. Class A shares are offered at net asset value
per share plus an initial sales charge. No sales charge applies on investments
of $1 million or more (and certain other qualified purchases) in Class A shares,
but a contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within up to
six years of purchase of Class B shares and a 1% contingent deferred sales
charge may be imposed on redemptions made within one year of purchase of Class C
shares. As approved by the Board of Trustees in 1997, Class B shares convert to
Class A shares eight years after the date they were purchased. The three classes
of shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions except that Class
B and Class C shares are subject to higher distribution fee rates than Class A
shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek capital appreciation together with
current income.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium--a high interest rate or yield--because of the increased risk of
loss. These securities can also be subject to greater price volatility.

The Fund also invests in foreign securities, which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business.

Equity securities are valued at the latest quoted sales prices as of the close
of trading on the New York Stock Exchange on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in mutual funds are valued at their net asset value as of the close
of the New York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund held securities with a value of $915 that were
valued in such a manner.

 20   MainStay Convertible Fund


Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income quarterly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the constant yield method over the life of the
respective securities or, in the case of a callable security, over the period to
the first date of call. Discounts and premiums on short-term securities are
accreted and amortized, respectively, on the straight line method. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 23) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. The Fund may not
have the right to demand that such securities be registered. Disposal of these
securities may involve time-consuming negotiations and expenses and it may be
difficult to obtain a prompt sale at an acceptable price. (See Note 5 on page
24.)

(I) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

providers that contain a variety of representations and warranties and which
provide general indemnifications. The Fund's maximum exposure under these
arrangements is unknown, as this would involve future claims that may be made
against the Fund that have not yet occurred. Based on experience, management is
of the view that the risk of loss in connection with these potential
indemnification obligations is remote. However, there can be no assurance that
material liabilities related to such obligations will not arise in the future
which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.60% on assets up to $500 million, 0.55% on assets from
$500 million to $1 billion and 0.50% on assets in excess of $1 billion. Prior to
August 1, 2007, the Fund was contractually obligated to pay the Manager a
monthly fee for services performed and facilities furnished at an annual rate of
the Fund's average daily net assets as follows: 0.72% on assets up to $500
million, 0.67% on assets from $500 million to $1 billion and 0.62% on assets in
excess of $1 billion. NYLIM had voluntarily agreed to waive its management fee
by 0.05% to 0.67% on assets up to $500 million to 0.62% on assets from $500
million to $1 billion and to 0.57% on assets in excess of $1 billion, which is
not recoupable.

Effective August 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.175%; Class B, 1.925%; and Class C, 1.925%. This expense
limitation may be modified or terminated only with the approval of the Board of
Trustees. NYLIM may recoup the amount of any management fee waivers or expense
reimbursements from the Fund pursuant to the agreement if such action does not
cause the Fund to exceed existing expense limitations and the recoupment is made
within three years after the year in which NYLIM incurred the expense. Between
March 1, 2007 and August 1, 2007, NYLIM had entered into a written expense
limitation agreement under which it had agreed to waive a portion of the Fund's
management fee or reimburse the expenses of the appropriate class of the Fund so
that the class' total ordinary operating expenses (total annual operating
expenses excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) did not exceed the following amounts of average daily net
assets for each class: Class A, 1.20%; Class B, 1.95%; and Class C, 1.95%.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $3,377,137 and waived its fees in the amount of $474,044 of which
$291,912 is recoupable.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
         OCTOBER 31,
   2008*       2009      2010       TOTAL
                      
$213,955   $701,502  $291,912  $1,207,369
- -----------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, the Manager had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.20% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's

 22   MainStay Convertible Fund


administrative operations. For providing these services to the Fund, SSBT is
compensated by NYLIM.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $56,454 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $1,758, $145,948 and $2,130, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $1,301,359.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>
                                                    
Class A                                   $290,026          0.1%
- ------------------------------------------------------------------
Class C                                        150          0.0*
- ------------------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(G) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $18,272.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $75,686 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

The difference between book-basis and tax basis unrealized appreciation is
primarily due to wash sale deferrals.

The other temporary differences are primarily due to defaulted bond releases,
tax treatment of Contingent Obligations, and unreversed wash sale deferrals.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income and accumulated net
realized gain on investments, arising from permanent differences; net assets at
October 31, 2007 are not affected.

NOTE 10--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts. The MainStay Equity Index Fund is not a
portfolio of Eclipse Funds Inc.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, on going analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Convertible Fund ("the Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2007, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years in the four-year period then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Convertible Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years in the four-year period then ended, in
conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADIVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's recent underperformance
and mixed performance over longer time periods.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund and from the
overall relationship with the Trust was low. The Trustees considered other
benefits that the Manager and its affiliates receive from the relationship with
the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder
Services receive in exchange for services they provide to the Funds, and certain
benefits from soft dollar arrangements. The Trustees acknowledged certain
benefits to the reputation of the Manager and the Trust from their association
with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

                                                    www.mainstayfunds.com     27


The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to reduce the
contractual management fee applicable to the Fund, with a corresponding
reduction to be made at each contractual breakpoint that would reduce the Fund's
management fee at asset levels above the breakpoints, and the fact that the
breakpoints were intended to provide that shareholders would share in benefits
from economies of scale obtained through the growth in the Fund's assets. The
Trustees noted that the Fund's management fee rate had been reduced slightly at
some points in the past year by the breakpoint schedule applicable to the Fund.
The Trustees reviewed information about the potential effect of asset growth on
Fund expenses, the difficulty of forecasting its effect on the profitability of
the Manager and its affiliates, and the management fee breakpoints applicable to
the Fund and certain other funds. It was noted that, to the extent the Fund's
gross expenses currently were higher than its net expenses,the reduction of the
Fund's gross expenses through the achievement of economies of scale might
benefit the Manager by reducing the expenses the Manager must reimburse to the
Fund rather than directly benefiting the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees took account of the Manager's willingness to maintain the management
fee waiver and expense limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Performance figures reflect
certain fee waivers and/or expense limitations, without which total returns may
have been lower. These fee waivers and/or expense limitations are contractual
and may be modified or terminated only with the approval of the Board of
Trustees. The Manager may recoup the amount of certain management fee waivers or
expense reimbursements from the Fund pursuant to the contract if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which the Manager
incurred the expense. From inception (2/28/97) through 8/31/98, performance for
Class C shares (first offered 9/1/98), includes the historical performance of
Class B shares adjusted to reflect the applicable CDSC, fees, estimated expenses
and fee waivers/expense limita-

   Brothers(R) Aggregate Bond Index, securities must be U.S. dollar denominated
   and investment grade and have a fixed-rate coupon, a remaining maturity of at
   least one year, and a par amount outstanding of at least $250 million.
   Results assume reinvestment of all income and capital gains. An investment
   cannot be made directly in an index. The Lehman Brothers(R) Aggregate Bond
   Index is considered to be the Fund's broad-based securities-market index for
   comparison purposes.
2. The Fund's Three-Index Composite assumes equal investments in the Lehman
   Brothers(R) Aggregate Bond Index, the Credit Suisse High Yield Index, and the
   Citigroup Non-U.S. Dollar World Government Bond Index. All indices are
   unmanaged. The indices measure the performance of securities in the U.S.
   government and domestic investment-grade bond sector, the U.S. high-yield
   bond sector and the international bond sector, respectively. Results assume
   that all income and capital gains are reinvested in the index or indices that
   produce them. An investment cannot be made directly in an index or this

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY DIVERSIFIED INCOME FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Joseph Portera and J. Matthew Philo,
CFA, of MacKay Shields LLC

HOW DID MAINSTAY DIVERSIFIED INCOME FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Diversified Income Fund returned 7.14% for
Class A shares, 6.23% for Class B shares and 6.23% for Class C shares for the 12
months ended October 31, 2007. Over the same period, the Fund's Class I shares
returned 7.50%. Class A and Class I shares outperformed--and Class B and Class C
shares underperformed--the 6.49% return of the average Lipper(1) multi-sector
income fund for the 12-month reporting period. All share classes outperformed
the 5.38% return of the Lehman Brothers(R) Aggregate Bond Index(2) and
underperformed the 7.86% return of the Fund's Three-Index Composite(3) for the
12 months ended October 31, 2007. The Lehman Brothers(R) Aggregate Bond Index is
the Fund's broad-based securities-market index. See page 5 for Fund returns with
sales charges.

WHAT KEY FACTORS AFFECTED THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

Timely asset allocation drove the Fund's relative performance during the
reporting period. Our decision to gradually increase the Fund's position in
emerging-market debt had a positive impact, as emerging-market debt rallied
early in the period and outperformed other fixed-income sectors during the
summer sell-off, when the fallout from nonperforming subprime-mortgage loans
began to roil the broader bond market. In emerging debt markets, we added
securities denominated in local currencies. The move helped results, because
local currency emerging-market bonds generally fared better than
developed-market debt during the reporting period.

We took advantage of the run-up in stock prices early in the first half of the
reporting period, and we sold the Fund's convertible bond holdings at a profit
before the stock market sell-off. After the downturn, we resumed making
convertible-bond purchases.

Our decision to avoid subprime-mortgage debt was also fortuitous in light of
credit difficulties that unfolded during the reporting period. Indeed, the Fund
was not directly involved in the shakeout in residential lending. During the
reporting period, several high-profile subprime-mortgage-loan originators either
closed because of capital constraints or were sold to larger entities. Lax
underwriting standards in 2006 were largely responsible for unprecedented
delinquencies in 2007.

Our decision to hedge the Fund's G7 currency exposure led to mixed results.(4)
During the subprime-mortgage crisis, the U.S. bond market experienced a "flight
to quality," or general a movement toward lower-risk fixed-income securities.
This trend, along with monetary easing by the Federal Open Market Committee,
supported a strong G7 government-bond rally toward the end of the reporting
period.

HOW DID YOU ALLOCATE THE FUND'S HOLDINGS WITHIN THE HIGH-YIELD MARKET?

In the high-yield market, our bottom-up investment process remained consistent.
We built a diversified portfolio of credits that presented a required margin of
safety against default and a catalyst for credit improvement over time.
Throughout the reporting period, we found credit risk to be mispriced in
general. In our opinion, the market was not presenting sufficient compensation,
on average, for assuming additional risk within the asset class. As a result,
the Fund was underweight in the lowest-rated high-yield credits throughout the
reporting period. Maintaining a cautious approach to the high-yield market
helped the Fund's performance overall, as high-yield portion of the Fund
outperformed the high-yield market toward the end of the reporting period.


Funds that invest in bonds are subject to credit, inflation and interest-rate
risk and can lose principal value when interest rates rise. Foreign securities
may be subject to greater risks than U.S. investments, including currency
fluctuations, less-liquid trading markets, greater price volatility, political
and economic instability, less publicly available information, and changes in
tax or currency laws or monetary policy. These risks are likely to be greater in
emerging markets than in developed markets. High-yield debt securities ("junk
bonds") are generally considered speculative because they present a greater risk
of loss than higher-quality debt securities and may be subject to greater price
volatility. The Fund may invest in derivatives, which may increase the
volatility of the Fund's net asset value and may result in a loss to the Fund.
The Fund may experience a portfolio turnover of more than 100% and may generate
taxable short-term capital gains.

   France, Germany, Italy, Japan, the United Kingdom and the United States--that
   meets to ensure the stability of the international financial system. Russia
   joined the group in 1998, creating the G8, but financial issues continue to
   be addressed by the G7.

HOW DID YOU MANAGE THE FUND'S POSITION IN EMERGING-MARKET DEBT DURING THE
REPORTING PERIOD?

We used a combination of top-down and bottom-up credit analysis for asset
allocation and security selection in the emerging markets. We continued to see
good fundamental and technical support for the asset class and increased the
Fund's weighting in emerging-market debt. Specifically, we found value in local
currency sovereign and corporate debt as well as in U.S. dollar denominated
debt. We reduced the Fund's exposure to corporate and sovereign investment-grade
debt to fund these emerging-market debt purchases. The Fund's increased
allocation to emerging-market debt contributed significantly to the Fund's yield
and, as mentioned earlier, was an important driver of its relative performance
during the reporting period.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

We added to or established meaningful positions during the reporting period in
the bonds of Community Health Systems, Reliant Energy and TXU Energy. We reduced
or eliminated significant positions in fixed-income securities of Chiquita
Brands International, GMAC LLC and Jean Coutu Group.

DID YOU MAKE ANY SIGNIFICANT WEIGHTING CHANGES DURING THE REPORTING PERIOD?

During the reporting period, we significantly increased the Fund's weighting in
emerging-market debt and reduced the Fund's exposure to developed-market
government debt. The Fund's weighting in high-yield debt remained relatively
steady, and we successfully navigated the convertible-bond sector, by selling
before the market traded lower.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

In the high-yield segment of the market, the Fund was overweight in the health
care and energy sectors and underweight in consumer discretionary, especially
home builders and retail. In the investment-grade segment, the Fund was
underweight in mortgage-backed securities. Toward the end of the reporting
period, we reduced the Fund's position in U.S. Treasury securities to sharply
underweight. In the non-dollar and emerging-market debt segments, we favored
corporate debt over government debt.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay
Diversified Income Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares and Class B
shares commenced on February 28, 1997. Class C shares commenced on September 1,
1998. Class I shares commenced on January 2, 2004. Class A shares are offered at
net asset value per share plus an initial sales charge. No sales charge applies
on investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within up to six years of purchase of Class B shares and a 1% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are not subject to a sales charge. As
approved by the Board of Trustees in 1997, Class B shares convert to Class A
shares eight years after the date they were purchased. The four classes of
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that Class B and
Class C shares are subject to higher distribution fee rates than Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution or service fee.

The Fund's investment objective is to provide current income and competitive
overall return by investing primarily in domestic and foreign debt securities.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium--a high interest rate or yield--because of the increased risk of
loss. These securities can also be subject to greater price volatility.

The Fund invests in foreign securities, which carry certain risks that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business.

Equity securities are valued at the latest quoted sales prices as of the close
of trading on the New York Stock Exchange on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Options contracts are valued at the last posted settlement price on the market
where such options are principally traded. Investments in mutual funds are
valued at their net asset value as of the close of the New York Stock Exchange
on the date of valuation.

Foreign currency forward contracts are valued at their fair market values
determined on the basis of the mean between the last current bid and ask prices
based on dealer or exchange quotations.

Loans are valued at the average of bid quotations obtained from a pricing
service. The Trust has engaged an independent pricing service to provide market
value quotations from dealers in loans. As of October 31, 2007, 100% of total
investments in loans were valued based on prices from such services.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity

 32   MainStay Diversified Income Fund


and non-equity securities which may be valued in this manner include, but are
not limited to: a security the trading for which has been halted or suspended; a
debt security that has recently gone into default and for which there is not a
current market quotation; a security of an issuer that has entered into a
restructuring; a security that has been de-listed from a national exchange; a
security the market price of which is not available from an independent pricing
source or, if so provided, does not, in the opinion of the Fund's investment
adviser or sub-adviser (if applicable), reflect the security's market value; a
security where the trading on that security's principal market is temporarily
closed at a time when, under normal conditions, it would be open. At October 31,
2007, the Fund held securities with a value of $455,547 that were valued in such
a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income monthly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the constant yield method over the life of the
respective securities or, in the case of a callable security, over the period to
the first date of call. Discounts and premiums on short-term securities are
accreted and amortized, respectively, on the straight line method. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 36) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are canceled in closing

                                                    www.mainstayfunds.com     33

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

purchase transactions are added to the proceeds or netted against the amount
paid on the transaction to determine the realized gain or loss. By writing a
covered call option, in exchange for the premium, the Fund foregoes the
opportunity for capital appreciation above the exercise price should the price
of the underlying security or foreign currency increase. By writing a covered
put option, the Fund, in exchange for the premium, accepts the risk of a decline
in the market value of the underlying security or foreign currency below the
exercise price. A call option may be covered by the call writer's owning the
underlying security throughout the option period. A call option may also be
covered by the call writer's maintaining liquid assets valued at greater than
the exercise price of the call written. When writing a covered call option, the
Fund, in return for the premium on the option, gives up the opportunity to
profit from a price increase in the underlying securities above the exercise
price, but, as long as the obligation as the writer continues, has retained the
risk of loss should the price of the underlying security decline. After writing
a put option, the Fund may incur a loss equal to the difference between the
exercise price of the option and the sum of the market value of the underlying
security plus the premium received from the sale of the option.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(H) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate ("LIBOR").

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. For example, the Fund may be
contractually obligated to receive approval from the agent bank and/or borrower
prior to the sale of these investments.

The Fund assumes the credit risk of the borrower, the selling participant and
any other persons interpositioned between the Fund and the borrower
("intermediate participants"). In the event that the borrower, selling
participant or intermediate participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
borrower. At any point in time, up to the maturity date of the issue, the
borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(I) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. (See Note 5 on page 38.)

(J) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
rates last quoted by any major U.S. bank at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

 34   MainStay Diversified Income Fund


The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(K) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the Portfolio of Investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, the Fund forgoes principal and interest paid on the securities. The Fund
is compensated by the difference between the current sales price and the forward
price for the future as well as by the earnings on the cash proceeds of the
initial sale. MDRs may be renewed without physical delivery of the securities
subject to the contract. The Fund maintains liquid assets from its portfolio
having a value not less than the repurchase price, including accrued interest.
MDR transactions involve certain risks, including the risk that the MBS returned
to the Fund at the end of the roll, while substantially similar, could be
inferior to what was initially sold to the counterparty.

(L) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(M) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. The Fund may not
have the right to demand that such securities be registered. Disposal of these
securities may involve time-consuming negotiations and expenses and it may be
difficult to obtain a prompt sale at an acceptable price. (See Note 5 on page
38.)

(N) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.60% on assets up to $500 million and 0.55% on assets in
excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or

                                                    www.mainstayfunds.com     35

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

reimburse the expenses of the appropriate class of the Fund so that the class'
total ordinary operating expenses (total annual operating expenses excluding
taxes, interest, litigation, extraordinary expenses, and brokerage and other
transaction expenses relating to the purchase or sale of portfolio investments)
do not exceed the following amounts of average daily net assets for each class:
Class A, 1.30%; Class B, 2.05%; Class C, 2.05%; and Class I, 0.96%. This expense
limitation may be modified or terminated only with the approval of the Board of
Trustees. NYLIM may recoup the amount of any management fee waivers or expense
reimbursements from the Fund pursuant to the agreement if such action does not
cause the Fund to exceed existing expense limitations and the recoupment is made
within three years after the year in which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $665,009 and waived its fees in the amount of $93,916.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

- -----------------------------------------------------------------------------------------------------
</Table>

*  The expense limitation agreement became effective in 2005 and the recoupments
   will start to expire in 2008.

Prior to March 1, 2007, the Manager had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.30% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $18,149 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $497, $47,296, and $2,601, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $289,719.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held

 36   MainStay Diversified Income Fund


(G) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $4,107.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $37,750 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>

 --------------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals, straddle loss deferrals, and mark to
market on foreign currency forward contracts.

The other temporary differences are primarily due to distribution payables and
interest on defaulted securities.

The following table discloses the current year reclassifications between
accumulated undistributed net investment income, accumulated net realized loss
on investments and additional paid-in capital, arising from permanent
differences; net assets at October 31, 2007 are not affected.

 -----------------------------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to foreign currency gain
(loss), prior year post financial adjustments, straddles, reclassification of
consent payment and paydown gain (loss).

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $4,317,631 were available as shown in the table below, to the extent provided
by the regulations to offset future realized gains of the Fund through the years
indicated. To the extent that these loss carryforwards are used to offset future
capital gains, it is probable that the capital gains so offset will not be
distributed to shareholders.

NOTE 10--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund as well as the related guarantee disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance of the outcome
of these efforts.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Diversified Income Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year period
then ended, and the financial highlights for each of the years or periods in the
four-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Diversified Income Fund of The MainStay Funds as of October 31, 2007,
the results of its operations for the year then ended, the changes in its net
assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years or periods in the four-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's generally mid-range
recent investment performance and its underperformance relative to peer funds
over the longer term.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund and from the
overall relationship with the Trust was low. The Trustees considered other
benefits that the Manager and its affiliates receive from the relationship with
the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder
Services receive in exchange for services they provide to the Funds, and certain
benefits from soft dollar arrangements. The Trustees acknowledged certain
benefits to the reputation of the Manager and the Trust from their association
with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the

 42   MainStay Diversified Income Fund


Fund's assets, or the assets of the Trust overall, increase. The Trustees noted,
in particular, the plans of the Manager and its affiliates for marketing and
distributing the shares of the various series of the Trust. They noted the
Manager's willingness to implement a contractual breakpoint that would reduce
the Fund's management fee at asset levels above the breakpoint, and the fact
that the breakpoint was intended to provide that shareholders would share in
benefits from economies of scale obtained through the growth in the Fund's
assets. The Trustees noted that the Fund not reached the asset level at which
the breakpoint would reduce the Fund's management fee rate. The Trustees
reviewed information about the potential effect of asset growth on Fund
expenses, the difficulty of forecasting its effect on the profitability of the
Manager and its affiliates, and the management fee breakpoints applicable to the
Fund and certain other funds.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered that comparative data with respect to other
clients of the Manager or Subadvisor was not available as such clients did not
have similar investment mandates as the Fund. The Trustees considered the
current and proposed contractual and net management fees, its anticipated
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationships among the Manager, the Subadvisor and the Trust and the
likely difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager. The Trustees noted the Manager's
agreement to maintain a limit on the Fund's net expenses at a certain level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The dividends paid by the Fund during the fiscal year ended October 31, 2007,
should be multiplied by 0.4% to arrive at the amount eligible for qualified
dividend income, 57.6% for qualified interest income and 0.4% for the corporate
dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will
be the amounts you are to use on your federal income tax return and will differ
from the amounts which we must report for the Fund's fiscal year ended October
31, 2007.

TRUSTEES AND OFFICERS

The Trustees oversee the Fund, the Manager and the Subadvisor. Pursuant to
notice, a Special Meeting of Shareholders of the Trust was held on May 4, 2007,
at NYLIM's offices in Parsippany, New Jersey. The Trustees listed below were
elected to serve the Trust effective June 7, 2007.

Each Trustee serves until his or her successor is elected and qualified or until

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graph assumes an initial investment of $10,000 and reflects the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 3% and an annual 12b-1
fee of .25%. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. These fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. The Manager may recoup the
amount of certain management fee waivers or expense reimbursements from the Fund
pursuant to the contract if such action does not cause the Fund to exceed
existing expense limitations and the recoupment is made within three years after
the year in which the Manager incurred the expense.
1. Performance figures shown reflect nonrecurring reimbursements from affiliates
   for professional fees and losses attributable to shareholder trading
   arrangements. If these nonrecurring reimbursements had not been made the
   total return (excluding sales charges) would have been 13.03% for the
   five-year period ended October 31, 2007, and 6.28% for the ten-year period
   then ended.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EQUITY INDEX FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Francis J. Ok of New York Life
Investment Management LLC

HOW DID MAINSTAY EQUITY INDEX FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, Class A shares of MainStay Equity Index Fund
returned 13.83% for the 12 months ended October 31, 2007. The Fund, which offers
only one share class, underperformed the 13.92% return of the average Lipper(1)
S&P 500 Index objective fund and the 14.56% return of the S&P 500(R) Index(2)
for the 12 months ended October 31, 2007. Because the Fund incurs operating
expenses that a hypothetical index does not, there will be times when the Fund's
performance lags that of the Index. The S&P 500(R) Index is the Fund's broad-
based securities-market index. See page 5 for Fund returns with sales charges.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES WERE THE STRONGEST CONTRIBUTORS TO
THE FUND'S PERFORMANCE AND WHICH WERE THE WEAKEST CONTRIBUTORS?

On the basis of impact, which takes weightings and total returns into account,
the industry that made the strongest positive contribution to the Fund's
performance was oil, gas & consumable fuels. Computers & peripherals was the
second-strongest contributor, and energy equipment & services was third. The
industry that made the weakest contribution to the Fund's performance was
commercial banks. The second-weakest contributor was thrifts & mortgage finance,
followed by specialty retail.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES HAD THE HIGHEST TOTAL RETURNS AND
WHICH HAD THE LOWEST?

In terms of total return, the best-performing industry in the S&P 500(R) Index
was construction & engineering, followed by Internet & catalog retail and auto
components. During the reporting period, thrifts & mortgage finance recorded the
lowest total return of any industry in the Index. Real estate management &
development had the second-lowest total return, followed by household durables.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST POSITIVE CONTRIBUTORS TO THE FUND'S
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH WERE THE GREATEST DETRACTORS?

On the basis of impact, which takes weightings and total returns into
consideration, the stocks that made the greatest positive contributions to the
Fund's performance during the reporting period were Exxon Mobil, Apple and
General Electric. The weakest contributor was Citigroup, followed by Amgen and
Comcast.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS HAD THE HIGHEST TOTAL
RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Within the S&P 500(R) Index, the stock with the highest total return during the
12-month reporting period was National Oilwell Varco. Apple was second, followed
by Amazon.com. The individual Fund holding with the lowest total return for the
reporting period was Circuit City Stores, followed by MGIC Investment and
Countrywide Financial.

WERE THERE ANY CHANGES TO THE MAKEUP OF THE S&P 500(R) INDEX DURING THE
REPORTING PERIOD?

During the 12-month reporting period, there were 44 additions to the S&P 500(R)
Index and 44 deletions from it. Notable additions to the Index were Covidien and
Tyco Electronics, both of which were added when the companies were spun off from
Tyco International. Mellon Financial was a significant deletion during the
period. The deletion occurred when Mellon Financial was acquired by Bank of New
York.


The Fund was closed to new investors and new purchases as of January 1, 2002.
Index funds generally seek to reflect the performance of an index or an
allocation among indices, unlike other funds, whose objectives may, in some
cases, involve seeking to outperform an index or other benchmark. The Fund seeks
to track the performance and weightings of stocks in the S&P 500(R) Index. The
Index itself, however, may change from time to time as companies merge, divest
units, add to their market capitalization or face financial difficulties. In
addition, Standard & Poor's may occasionally adjust the Index to better reflect
the companies that Standard & Poor's believes are most representative of the
makeup of the U.S. economy. The Fund may invest in derivatives, which may
increase the volatility of the Fund's net asset value and may result in a loss
to the Fund.

 20 MainStay Equity Index Fund      The notes to the financial statements are an
integral part of, and should be read in conjunction with, the financial
statements.


NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Equity
Index Fund (the "Fund"). The Board of Trustees of the Trust approved the closure
of the Fund to new investors and new share purchases effective January 1, 2002.
Existing shareholders are permitted to reinvest dividends only and NYLIFE LLC
will continue to honor the unconditional guarantee associated with the Fund.
(See Note 10 on page 25.)

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance (and reflect reinvestment of
dividends) of publicly traded common stocks represented by the S&P 500(R) Index.
When formed the Fund was sub-classified as a "non-diversified" fund, which meant
that it could invest a greater percentage of its assets than other funds in a
particular issuer. However, due to the Fund's principal investment strategy and
investment process, it has historically operated as a "diversified" fund.
Therefore, the Fund will not operate as a "non-diversified" fund without first
obtaining shareholder approval.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Futures
contracts are valued at the last posted settlement price on the market where
such futures are primarily traded. Investments in mutual funds are valued at
their net asset value as of the close of the New York Stock Exchange on the date
of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007 the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

The Fund declared a dividend of $0.7133 per share which was paid on December 12,
2007, and also underwent a reverse share split on that day. The reverse share
split rate was 0.98617 per share outstanding calculated on fund shares
outstanding immediately after reinvestment of dividends.

Certain amounts in the Financial Highlights and Notes to Financial Statements
(See Note 9 on page 25.) have been adjusted to reflect the cumulative effects of
this reverse stock split and those that occurred in each of the periods
presented.

                                                      www.mainstayfunds.com   21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 23) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a securities
index. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. The Fund invests in stock index futures
contracts to gain full exposure to changes in stock market prices to fulfill its
investment objective.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.

(H) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(I) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("NYLIM" or "Manager") a
registered investment adviser and an indirect wholly-owned subsidiary of New
York Life Insurance Company ("New York Life"), serves as the Fund's Manager.
NYLIM provides offices and conducts clerical, recordkeeping and bookkeeping
services, and is responsible for the financial and accounting records required
to be maintained by the Fund. NYLIM also pays the salaries and expenses of all
personnel affiliated with the Fund and all the operational expenses that are not
the responsibility of the Fund. The Fund is advised by the Manager directly,
without a Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.25% on assets up to $1.0 billion, 0.225% on assets from
$1.0 billion to $3.0 billion and 0.20% on assets

 22 MainStay Equity Index Fund


in excess of $3.0 billion. NYLIM has also contractually agreed to waive its
management fee by 0.06% to 0.19% on assets up to $1.0 billion, to 0.165% on
assets from $1.0 billion to $3.0 billion and to 0.14% on assets in excess of
$3.0 billion which is not recoupable.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the Fund so that the total ordinary operating
expenses (total annual operating expenses excluding taxes, interest, litigation,
extraordinary expenses, and brokerage and other transaction expenses relating to
the purchase or sale of portfolio investments) do not exceed 0.60% of the
average daily net assets of the Fund. NYLIM may recoup the amount of any
management fee waiver or expense reimbursement from the Fund pursuant to the
agreement if such action does not cause the Fund to exceed the expense
limitations and the recoupment is made within three years after the year in
which NYLIM incurred the expense. This expense limitation may be modified or
terminated only with the approval of the Board of Trustees.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $1,188,183 and waived expenses in the amount of $688,252 of which
$403,088 is recoupable.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
           OCTOBER 31,
   2008*          2009       2010        TOTAL
                           
$209,184   $   420,903   $403,088   $1,033,175
- ----------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENT FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 10 on
page 25.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $60,567. Additional payments were
made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION FEES.  The Trust, on behalf of the Fund, has a Distribution
Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect
wholly-owned subsidiary of New York Life. The Fund has adopted a distribution
plan (the "Plan") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Plan, the Distributor receives a monthly distribution fee from
the Fund at an annual rate of 0.25% of the Fund's average daily net assets,
which is an expense of the Fund for distribution or service activities as
designated by the Distributor.

The Plan provides that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $734,863.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $17,759.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of

                                                      www.mainstayfunds.com   23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

1% of the next $80 million of average monthly net assets and 1/100 of 1% of any
amount in excess of $100 million of average monthly net assets. Fees for these
services provided to the Fund by the Manager amounted to $74,194 for the year
ended October 31, 2007.

The difference between book-basis and tax basis unrealized appreciation is
primarily due to wash sales deferrals.

The following table discloses the current year reclassifications between
accumulated undistributed net investment income, accumulated net realized gain

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $41,750,743 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

NOTE 5--CUSTODIAN:

SSBT is the custodian of cash and securities of the Fund. Custodial fees are
charged to the Fund based on the market value of securities in the Fund and the
number of certain cash transactions incurred by the Fund.

NOTE 6--LINE OF CREDIT:

The Fund, and certain affiliated funds, maintain a line of credit of
$160,000,000 with a syndicate of banks in order to secure a source of funds for
temporary purposes to meet unanticipated or excessive shareholder redemption
requests. These funds pay a commitment fee, at an annual rate of .060% of the
average commitment amount, regardless of usage, to The Bank of New York, which
acts as agent to the syndicate. Such commitment fees are allocated among the
funds based upon net assets and other factors. Interest on any revolving credit
loan is charged based upon the Federal Funds Advances rate. There were no
borrowings made or outstanding on the line of credit during the year ended
October 31, 2007.

NOTE 7--PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2007, purchases and sales of securities, other
than short-term securities, were $21,646 and $125,349, respectively.

NOTE 9--GUARANTEE:

NYLIFE LLC ("NYLIFE"), a wholly-owned subsidiary of New York Life, will
guarantee unconditionally and irrevocably pursuant to a Guaranty Agreement
between NYLIFE and the Fund (the "Guarantee") that if, on the business day
immediately after ten years from the date of purchase

 24 MainStay Equity Index Fund


(the "Guarantee Date"), the net asset value ("NAV") of a Fund share plus the
value of all dividends and distributions paid, including cumulative reinvested
dividends and distributions attributable to such share paid during that ten-year
period ("Guaranteed Share"), is less than the price initially paid for the Fund
share ("Guaranteed Amount"), NYLIFE will pay shareholders an amount equal to the
difference between the Guaranteed Amount for each such Guaranteed share
outstanding and held by shareholders as of share and the net asset value of each
such of the close of business on the Guarantee Date. For the services that NYLIM
and its affiliates provide to the Fund, they receive the fees described in the
prospectus (see Note 3 on page 22). Neither NYLIM nor its affiliates receive a
separate fee for providing the Guarantee, although the Guarantee has been
considered in connection with the annual renewal of the management fee.

NOTE 10--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the MainStay
Equity Index Fund was $516,000. NYLIM has reimbursed or paid all expenses
relating to the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENT:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Equity Index Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years in the four-year period then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Equity Index Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years in the four-year period then ended, in
conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") (the
"Agreement") at a meeting held on May 22 and 23, 2007. In connection with the
approval of the Agreement, the Trustees reviewed a significant amount of a wide
variety of information that they had requested and received from the Manager,
and data and analysis from an outside data provider and a third party
consultant. In their deliberations, the Trustees considered various regulatory
developments and industry trends, including the reduction of fees or net expense
ratios by certain other equity index funds. In considering approval of the
Agreement, and in evaluating the fairness of the compensation to be paid by the
Fund, the Trustees met both as a full Board and in executive session with no
Interested Trustee present, in advance of the meeting at which the Agreement was
approved, and they considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager. The Trustees reviewed the services that the Manager
have provided historically to the Fund, and also generally to other series of
the Trust. Among other services, the Manager's services have included investment
management services--which include, but are not limited to, monitoring and
evaluating the Fund's investment program and investment results, providing the
day-to-day portfolio management of the Fund, determining the composition of
assets of the Fund and the timing of the Fund's execution of the purchase and
sale of assets, and the Fund's compliance with its investment policies and
restrictions--and administrative services, including working with other service
providers of the Trust, maintaining certain Fund records, providing office
space, managing reverse stock splits, performing clerical and bookkeeping
services for the Fund, preparing Board materials and Fund filings, and otherwise
managing the Trust's operations. The Trustees considered, among other things,
the Manager's management, personnel, resources, operations and portfolio
management capabilities. The Board reviewed reports on the Manager's brokerage
practices, including with respect to best execution of portfolio trades. The
Trustees considered the Manager's supervision of the Fund's service providers
and its attention to the compliance program of the Trust, the Manager, and
certain other service providers. The Trustees noted the generally favorable
results of a third party review of the services and communications that NYLIM
Service Company LLC, an affiliate of the Manager, has provided to Trust
shareholders. The Trustees acknowledged the guarantee feature and the role of an
affiliate of the Manager with regard to the guarantee.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's investment results
that, consistent with its investment objective, corresponded to the total return
performance of publicly traded common stocks represented by the S&P 500 Index,
the sensitivity to expenses of the comparative performance of the Fund, and the
Fund's net performance that was slightly lower than peer median over several
time periods considered.

The Trustees considered the cost to the Manager of the Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement, and from the overall relationship with
the Trust, was low. The Trustees considered other benefits that the Manager and
its affiliates receive from the relationship with the Trust, including benefits
that NYLIFE Distributors and MainStay Shareholder Services receive in exchange
for services they provide to the Funds, and certain benefits from soft dollar
arrangements. The Trustees acknowledged certain benefits to the reputation of
the Manager and the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. The Trustees noted that the Fund not reached the asset
level at which breakpoints would reduce the Fund's management fee rate, that the
Fund's assets had decreased in recent years, and that the Fund can reach the
breakpoints' asset levels only through capital appreciation so long as the Fund
remains closed to new share purchases. The Trustees reviewed information about
the potential effect of asset growth on Fund expenses, the difficulty of
forecasting its effect on the profitability of the Manager and its affiliates,
and the management fee breakpoints applicable to the Fund and certain other
funds. It was noted that, to the extent the Fund's gross expenses currently were
higher than its net expenses, the reduction of the Fund's gross expenses through
the achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses. The Trustees considered information about
transfer agency expenses and their effect on the Fund's overall expenses.

                                                      www.mainstayfunds.com   27


The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other registered fund clients of the Manager having investment strategies
similar to that of the Fund, and took account of explanations and other
information relating to the fees and expenses of those other funds and accounts.
The Trustees considered the current and proposed contractual and net management
fees, its anticipated gross and net expense ratio, and various components of the
expense ratio, in comparison to other funds in comparison groupings. The
Trustees generally acknowledged the historical relationship between the Manager
and the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees noted the Manager's agreement to continue to waive a certain portion of
its management fee and maintain the existing contractual limitation on the
Fund's net expenses.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreement. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering the Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of the Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of the Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. These fee waivers and/or
expense limitations are contractual and may be modified or terminated only with
the approval of the Board of Trustees. The Manager may recoup the amount of
certain management fee waivers or expense reimbursements from the Fund pursuant
to the contract if such action does not cause the Fund to exceed existing
expense limitations and the recoupment is made within three years after the year
in which the Manager incurred the expense. From inception (6/1/98) through
8/31/98, performance of Class C shares (first offered 9/1/98) includes the
historical performance of Class B shares adjusted to reflect the applicable
CDSC, estimated expenses, and fee waivers/expense limitations of Class C shares
upon initial offer. From inception (6/1/98) through 10/31/07, the performance of
Class I shares (first offered 8/31/07) includes the historical performance of
Class A shares adjusted to reflect the fees and expenses for Class I shares.
Unadjusted, the performance shown for the newer classes of shares might have
been lower.

   JPMorgan Emerging Markets Bond Index Global is an unmanaged index that tracks
   total returns for U.S. dollar denominated debt instruments--Brady bonds,
   loans and Eurobonds--issued by emerging-market sovereign and quasi-sovereign
   entities. The JPMorgan EMBI Global Diversified Index limits the weights of
   those index countries with larger debt stocks by only including specified
   portions of these countries' eligible current face amounts of debt
   outstanding. Results assume reinvestment of all income and capital gains. The
   JPMorgan EMBI Global Diversified Index is considered to be the Fund's
   broad-based securities-market index for comparison purposes. An investment
   cannot be made directly in an index.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GLOBAL HIGH INCOME FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   multiplied by the average account value over the period, divided by 365 and
   multiplied by 184 (to reflect the one-half year period).
2. Shares were first offered on August 31, 2007. Expenses paid during the period
   reflect ongoing costs for the since-inception period ending October 31, 2007.
   Had these shares been offered for the six months ended October 31, 2007, and
   had the Fund provided a hypothetical 5% annualized return, expenses paid
   during the period would have been $5.85 and the ending account value would
   have been $1,019.25.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Gary Goodenough, Joseph Portera and
Jeffrey H. Saxon of MacKay Shields LLC

HOW DID MAINSTAY GLOBAL HIGH INCOME FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Global High Income Fund returned 8.11% for
Class A shares, 7.28% for Class B shares and 7.28% for Class C shares for the 12
months ended October 31, 2007. Over the same period, the Fund's Class I shares
returned 7.84%. All share classes underperformed the 9.53% return of the average
Lipper(1) emerging markets debt fund for the 12-month reporting period. Class A
and Class I shares outperformed--and Class B and Class C shares
underperformed--the 7.72% return of the JPMorgan EMBI Global Diversified
Index,(2) the Fund's broad-based securities-market index, for the 12 months
ended October 31, 2007. See page 5 for Fund returns with sales charges.

WHAT FACTORS AFFECTED THE MANAGEMENT AND PERFORMANCE OF THE FUND DURING THE
REPORTING PERIOD?

Events in developed markets--including lower interest rates in the United
States, higher commodity prices and G7 economic activity--had a substantial
impact on emerging-market debt during the reporting period.

Early in the reporting period, we made a strategic decision to increase the
Fund's exposure to local currency debt. The decision--which was based on a
reduction of the spread in U.S. dollar bonds, strong trade and current-account
performance--contributed positively to the Fund's performance, as the U.S.
dollar showed a weakening bias for most of the reporting period.

Several other factors influenced emerging-market debt prices and Fund
performance during the reporting period. Subprime-mortgage woes led to spread
widening, and we used this as an opportunity to add credits with higher
volatility than the market as a whole. The Federal Open Market Committee decided
to cut the targeted federal funds rate in September and again at the end of
October 2007. These moves helped the Fund's performance, because yields retraced
some of the widening that had occurred in July and August. Higher commodity
prices led us to increase the Fund's exposure to the debt securities of
countries that export oil or have metals & mining interests.

HOW DID THE FUND'S LATIN AMERICAN HOLDINGS PERFORM?

Ecuador dollar bonds were strong performers when it became evident that the new
president would not attempt to renegotiate external debt. We sold the Fund's
Ecuador bonds at a profit early in 2007. Among higher-risk credits in our
investment universe, we showed a preference for Venezuelan bonds. We took
advantage of the summer turmoil to add sovereign exposure, and toward the end of
the period, the Fund added securities of Venezuela's state-owned oil company.

Brazilian sovereign debt performed well, propelled by strong economic growth,
fiscal discipline and a stable political environment. We increased the Fund's
overweight allocation to Brazilian debt, adding both local currency and U.S.
dollar denominated government and corporate debt. In most cases, these holdings
helped Fund returns. The exceptions were Brazilian airline bonds, which were the
worst-performing corporate debt in the Fund's portfolio. Following a major plane
crash in Sao Paolo, Brazil, local carriers TAM Capital and GOL Linhas Aereas
Inteligentes came under heavy selling pressure. We had sold the Fund's position
in GOL earlier in the year, which helped mitigate the negative effect of these
airline bonds on the Fund's performance.


Class I shares commenced operations on August 31, 2007.
Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets.
High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. The Fund may invest in
derivatives, which may increase the volatility of the Fund's net asset value and
may result in a loss to the Fund. Funds that invest in bonds are subject to
credit, inflation, and interest-rate risk and can lose principal value when
interest rates rise. The Fund may experience a portfolio turnover rate of more
than 100% and may generate taxable short-term capital gains. The Fund is
nondiversified. By concentrating in a smaller number of investments, the Fund's
risk is increased because each investment has a greater effect on the Fund's
performance.

   Diversified Index.
3. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The term may also refer to the difference in yield between two specific
   securities or types of securities at a given time.

WAS THE FUND INVESTED IN BANK DEBT DURING THE REPORTING PERIOD?

Historically, the Fund has not been a major buyer of bank debt. For bank debt to
be attractive, we need to feel comfortable with the sector and with the
regulatory framework. Kazakhstan bank paper met our criteria, and we purchased
it from a number of issuers early in the reporting period. The relative
performance of this bank paper was mixed. One of the Fund's holdings, ATF Bank,
was bought by an Italian bank and performed well. We added to the position
toward the end of the reporting period. The Fund's other Kazakhstan bank
holdings got caught in the global credit squeeze, and spreads widened
dramatically. We held on to these positions, however, expecting the nation's
central bank to support liquidity. We believed that at least one of these
holdings could be a potential takeover target.

WERE THERE ANY SIGNIFICANT CHANGES IN THE FUND'S COUNTRY OR REGIONAL WEIGHTINGS
DURING THE REPORTING PERIOD?

We gradually reduced the Fund's exposure to Russian sovereign debt during the
reporting period. We added Asian debt, mainly Chinese corporate issuers, to the
Fund during the 12 months ended October 31, 2007.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Global
High Income Fund (the "Fund").

The Fund currently offers four classes of shares. Class A shares and Class B
shares commenced on June 1, 1998. Class C shares commenced on September 1, 1998.
Class I shares commenced on August 31, 2007. Class A shares are offered at net
asset value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within up to six years of purchase of Class B shares and a 1% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are not subject to a sales charge. As
approved by the Board of Trustees in 1997, Class B shares convert to Class A
shares eight years after the date they were purchased. The four classes of
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that Class B and
Class C shares are subject to higher distribution fee rates than Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek to provide maximum current income by
investing primarily in high yield debt securities of non-U.S. issuers. Capital
appreciation is a secondary objective. The Fund is "non-diversified," which
means that it may invest a greater percentage of its assets than diversified
funds in a particular issuer. This may make it more susceptible than diversified
funds to risks associated with an individual issuer, and to single economic,
political or regulatory occurrences.

The Fund's principal investments include high yield securities (sometimes called
"junk bonds"), which are generally considered speculative because they present a
greater risk of loss, including default, than higher quality debt securities.
These securities pay a premium--a high interest rate or yield--because of the
increased risk of loss. These securities can also be subject to greater price
volatility.

The Fund also invests in foreign securities, which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business. Investments in mutual funds are valued at their net asset value as
of the close of the New York Stock Exchange on the date of valuation. Foreign
currency forward contracts are valued at their fair market values determined on
the basis of the mean between the last current bid and ask prices based on
dealer or exchange quotations.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security

 22   MainStay Global High Income Fund


where the trading on that security's principal market is temporarily closed at a
time when, under normal conditions, it would be open. At October 31, 2007, the
Fund held securities with a value of $1,569,440 that were valued in such a
manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income monthly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned using the effective interest rate method. Discounts and
premiums on securities purchased, other than short-term securities, for the Fund
are accreted and amortized, respectively, on the effective interest rate method
over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term securities are accreted and amortized, respectively, on the straight
line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 26) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are canceled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the price of the underlying security or foreign currency
increase. By writing a covered put option, the Fund, in exchange for the
premium, accepts the risk of a decline in the market value of the underlying
security or foreign currency below the exercise price. A call option may be
covered by the call writer's owning the underlying security throughout the
option period. A call option may also be covered by the call writer's
maintaining liquid assets valued at greater than the exercise price of the call
written. When writing a covered call option, the Fund, in return for the premium
on the option, gives up the opportunity to profit from a price increase in the
underlying securities above the exercise price, but, as long as the

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

obligation as the writer continues, has retained the risk of loss should the
price of the underlying security decline. After writing a put option, the Fund
may incur a loss equal to the difference between the exercise price of the
option and the sum of the market value of the underlying security plus the
premium received from the sale of the option.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(H) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund may invest in
loan assignments and loan participations. Loan assignments and participations
are agreements to make money available (a "commitment") to a borrower in a
specified amount, at a specified rate and within a specified time. Such loan
assignments and participations are typical senior, secured and collaterized in
nature. The Fund records an investment when the borrower withdraws money and
records interest as earned. These loans pay interest at rates which are
periodically reset by reference to a base lending rate plus a spread. These base
lending rates are generally the prime rate offered by a designed U.S. bank or
London InterBank Offered Rate ("LIBOR").

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. For example, the Fund may be
contractually obligated to receive approval from the agent bank and/or borrower
prior to the sale of these investments.

The Fund assumes the credit risk of the borrower, the selling participant and
any other persons interpositioned between the Fund and the borrower
("intermediate participants"). In the event that the borrower, selling
participant or intermediate participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
borrower. At any point in time, up to the maturity date of the issue, the
borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(I) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. (See Note 5 on page 27.)

(J) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
rates last quoted by any major U.S. bank at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

 24   MainStay Global High Income Fund


(K) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(L) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.
NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.70% on assets up to $500 million and 0.65% on assets in
excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.40%; Class B, 2.15%; Class C, 2.15%; and Class I, 1.15%.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. NYLIM may recoup the amount of any management fee waivers
or expense reimbursements from the Fund pursuant to the agreement if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which NYLIM incurred the
expense.

</Table>

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.40% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as

in the footnote relating to "Other Matters." (See Note 10 on page 28.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $23,939. Additional payments were
made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.
Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $56,134 the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $721, $81,741 and $17,757, respectively, for the year ended October
31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $537,867.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the

NOTE 10--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the MainStay
Global High Income Fund was $11,000. NYLIM has reimbursed or paid all expenses
relating to the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to

 28   MainStay Global High Income Fund


that fund's shareholders. Discussions have been held with the SEC concerning a
possible resolution of this matter. There can be no assurance of the outcome of
these efforts.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Global High Income Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2007, and the related statement of operations for the year or period then ended,
the statements of changes in net assets for each of the years or periods in the
two-year period then ended, and the financial highlights for each of the years
or periods in the four-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Global High Income Fund of The MainStay Funds as of October 31, 2007,
the results of its operations for the year or period then ended, the changes in
its net assets for each of the years or periods in the two-year period then
ended, and the financial highlights for each of the years or periods in the
four-year period then ended, in conformity with U.S. generally accepted
accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's mid-range investment
performance relative to peer funds over various time periods considered.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate
to low, and from the overall relationship with the Trust, was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

                                                    www.mainstayfunds.com     31


The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at asset
levels above the breakpoint, and the fact that the breakpoint was intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund not reached the asset level at which the breakpoint would reduce the Fund's
management fee rate. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including separate institutional
accounts having investment strategies similar to that of the Fund, and took
account of explanations and other information relating to the fees and expenses
of those other funds and accounts. The Trustees considered the current and
proposed contractual and net management fees, its anticipated gross and net
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationships among the Manager, the Subadvisor and the Trust and the
likely difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager. The Trustees took account of the
Manager's willingness to maintain the management fee waiver and expense
limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $4,667,916.

The dividends paid by the Fund during the fiscal year ended October 31, 2007,
should be multiplied by 1.0% to arrive at the amount eligible for qualified
interest income.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will
be the amounts you are to use on your federal income tax return and will differ
from the amounts which we must report for the Fund's fiscal year ended October
31, 2007.

                    Annual Report

                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Performance figures reflect
certain fee waivers and/or expense limitations, without which total returns may
have been lower. These fee waivers and/or expense limitations are contractual
and may be modified or terminated only with the approval of the Board of
Trustees. The Manager may recoup the amount of certain management fee waivers or
expense reimbursements from the Fund pursuant to the contract if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which the Manager
incurred the expense. From inception (5/1/86) through 8/31/98, performance of
Class C shares (first offered 9/1/98) includes the historical performance of
Class B shares adjusted to reflect the applicable sales charge (or CDSC), fees,
estimated expenses and fee waivers/expense limitations of Class C shares upon
initial offer. From inception (5/1/98) through 12/31/03, performance of Class I
shares (first offered 1/2/04) includes the historical performance of Class B
shares, adjusted to reflect the fees and expenses of Class I shares. Unadjusted,
the performance shown for the newer classes of shares might have been lower.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GOVERNMENT FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Gary Goodenough and Joseph Portera of
MacKay Shields LLC

HOW DID MAINSTAY GOVERNMENT FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK
DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Government Fund returned 4.67% for Class A
shares, 3.77% for Class B shares and 3.89% for Class C shares for the 12 months
ended October 31, 2007. Over the same period, the Fund's Class I shares returned
5.31%. Class A and Class I shares outperformed--and Class B and Class C shares
underperformed--the 4.12% return of the average Lipper(1) general U.S.
government fund for the 12-month reporting period. All share classes
underperformed the 5.85% return of the Lehman Brothers(R) Government Bond
Index,(2) the Fund's broad-based securities-market index, for the 12 months
ended October 31, 2007. See page 5 for Fund returns with sales charges.

DURING THE REPORTING PERIOD, HOW WAS THE FUND POSITIONED RELATIVE TO ITS PEERS?

In an effort to maximize yield per unit of duration in the Fund,(3) we
de-emphasized Treasury securities relative to our assessment of holdings in the
median Lipper peer fund. Instead, we placed greater emphasis on single- and
multifamily residential mortgage-backed securities and on debentures issued or
guaranteed by government housing enterprises. These overweight positions helped
the Fund maintain a yield advantage relative to its peers. We invested around
the core with no more than a 10% allocation to non-government-related
securities, diversified among asset-backed securities, commercial
mortgage-backed securities and corporate bonds. These noncore allocations were
also positive sources of yield.

During the reporting period, the U.S. economy decelerated and economic data was
somewhat erratic. To avoid being misled by fluctuating and unpredictable data
(which can affect the direction of interest rates) and to neutralize the impact
of changing Treasury yields, we held the Fund's duration close to our duration
estimate for the median Lipper peer fund.

The Fund held a relatively modest allocation to Treasury Inflation-Protected
Securities (TIPS) during the reporting period. This positioning detracted from
the Fund's performance relative to peer funds with higher TIPS allocations. As
the price of crude oil rose, TIPS traded higher and outperformed nominal
Treasurys.

HOW DID YOU SEEK TO ENHANCE THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

Trading activity was modest during the reporting period. To maintain a stable
allocation to mortgage-backed securities, most of the trades involved the
reinvestment of principal prepayments back into the sector. We also sold several
of the Fund's positions in asset-backed securities when we saw little
opportunity for further spread contraction.(4)

Our tactical trades during the reporting period, such as expanding the Fund's
exposure to callable agency debentures, capitalized on the steeper yield curve
and the shift toward lower yields. Yields on shorter-term U.S. Treasury
securities fell during the reporting period, while yields on longer-term
Treasurys rose. This caused a steepening in the Treasury yield curve. It
appeared that investors in longer-maturity Treasurys were demanding greater
compensation when buying duration and that short-maturity buyers were trying to
anticipate Federal Open Market Committee cuts in the targeted federal funds
rate.

During the reporting period, the Fund's callable agency debentures served their
intended purpose as higher-yielding substitutes for short-duration Treasurys.
The Fund's allocation to Treasury securities, on the other hand, provided a
measure of stability during periods of market choppiness.


Investments in the Fund are not guaranteed, even though some of the Fund's
investments are guaranteed by the U.S. government or its agencies or
instrumentalities. The Fund may invest in derivatives, which may increase the
volatility of the Fund's net asset value and may result in a loss to the Fund.
The Fund may experience a portfolio turnover of more than 100% and may generate
taxable short-term capital gains. Funds that invest in bonds are subject to
interest-rate risk and can lose principal value when interest rates rise.

3. Duration is a measure of the price sensitivity of fixed-income investments to
   changes in interest rates. Duration is expressed as a number of years and is
   considered a more accurate sensitivity gauge than average maturity.
4. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The term may also refer to the difference in yield between two specific
   securities or types of securities at a given time.

WHAT OTHER STRATEGIES DID YOU EMPLOY DURING THE REPORTING PERIOD AND HOW DID
THEY AFFECT FUND PERFORMANCE?

The Fund was overweight in mortgage-backed securities that were backed by
15-year loan terms and had cash-flow profiles amenable to a steeper yield curve.
The Fund had a lighter allocation to higher-coupon mortgage-backed securities
than the Lehman Brothers(R) Aggregate Bond Index, and this positioning detracted
from results during the reporting period. On the other hand, the Fund's
underweight position in Ginnie Maes benefited performance when these bonds
underperformed comparable Fannie Mae and Freddie Mac securities.

Homeowners had fewer refinancing options during the period. Tighter underwriting
standards and slower home equity growth led to a moderation in housing stock
turnover. Declining prepayment rates proved favorable for the Fund's
interest-only mortgage-backed securities, which tend to rise in value as their
principal base is preserved. The Fund also benefited from modest direct exposure
to securitizations of subprime residential mortgages. The impact on the Fund was
minimal.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay
Government Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. Class I shares commenced on January 2, 2004.
Class A shares are offered at net asset value per share plus an initial sales
charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within up to six years of purchase of Class B
shares and a 1% contingent deferred sales charge may be imposed on redemptions
made within one year of purchase of Class C shares. Class I shares are not
subject to a sales charge. As approved by the Board of Trustees in 1997, Class B
shares convert to Class A shares eight years after the date they were purchased.
The four classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A shares under a distribution plan pursuant to Rule 12b-1 under
the 1940 Act. Class I shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek a high level of current income,
consistent with safety of principal.

The ability of issuers of debt securities held by the Fund to meet their
obligations may be affected by economic developments in a specific industry or
region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business. Investments in mutual funds are valued at their net asset value as
of the close of the New York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund held securities with a value of $1,025,879, that
were valued in such a manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income monthly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to

 20   MainStay Government Fund


income and gains are reclassified amongst undistributed net investment income,
accumulated net realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and includes gains
and losses from repayments of principal on mortgage-backed securities. Interest
income is accrued as earned using the effective interest rate method. Discounts
and premiums on securities purchased, other than short-term securities, for the
Fund are accreted and amortized, respectively, on the effective interest rate
method over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term securities are accreted and amortized, respectively, on the straight
line method. Income from payment-in-kind securities is recorded daily based on
the effective interest method of accrual.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 22) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the Portfolio of Investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, the Fund forgoes principal and interest paid on the securities. The Fund
is compensated by the difference between the current sales price and the forward
price for the future as well as by the earnings on the cash proceeds of the
initial sale. MDRs may be renewed without physical delivery of the securities
subject to the contract. The Fund maintains liquid assets from its portfolio
having a value not less than the repurchase price, including accrued interest.
MDR transactions involve certain risks, including the risk that the MBS returned
to the Fund at the end of the roll, while substantially similar, could be
inferior to what was initially sold to the counterparty.

(H) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(I) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

personnel affiliated with the Fund and all the operational expenses that are not
the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a
registered investment adviser and an indirect wholly-owned subsidiary of New
York Life, serves as subadvisor to the Fund and is responsible for the
day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.60% on assets up to $1 billion and 0.55% on assets in
excess of $1 billion. NYLIM has also contractually agreed to waive a portion of
its management fee by 0.10% to 0.50% on assets up to $1 billion and to 0.45% on
assets in excess of $1 billion, which is not recoupable.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.05%; Class B, 1.80%; Class C, 1.80%; and Class I, 0.40%.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. NYLIM may recoup the amount of any management fee waivers
or expense reimbursements from the Fund pursuant to the agreement if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which NYLIM incurred the
expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $1,762,637 and waived its fees in the amount of $866,712 of which
$572,938 is recoupable.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
           OCTOBER 31,
 2008*        2009         2010         TOTAL
                            
$302,892    $643,616     $572,938    $1,519,446
- ------------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.05% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $16,032 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $1,704, $93,528 and $1,876, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with

 22   MainStay Government Fund


Boston Financial Data Services pursuant to which it performs certain services
for which NYLIM Service is responsible. Transfer agent expenses incurred by the
Fund, for the year ended October 31, 2007, amounted to $1,109,619.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>

Class I                                      1,113       15.2
- -------------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(G) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $10,922.
The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $56,044 for the year ended
October 31, 2007.

The difference between book-basis and tax basis unrealized depreciation is
primarily due to premium amortization adjustments.

The other temporary differences are primarily due to distribution payable.

The following table discloses the current year reclassifications between
accumulated undistributed net investment income and accumulated net realized
loss on investments, arising from permanent differences; net assets at October
31, 2007 are not affected.

The reclassifications for the Fund are primarily due to paydowns gain (loss) and
expiration of capital loss carryforwards.

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $13,377,081 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains through the years
indicated. To the extent that these loss carryforwards are used to offset future
capital gains, it is probable that the capital gains so offset will not be
distributed to shareholders.

NOTE 9--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Government Fund and the
fees and expenses of that Fund, as well as the related guaranteed disclosure to
that fund's shareholders. Discussions have been held with the SEC concerning a
possible resolution of this matter. There can be no assurance at this time as to
the outcome of these efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes", an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Government Fund ("the Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2007, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Government Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years or periods in the four-year period then ended,
in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's recent investment
performance that was better than peer median and its slightly lagging
performance over longer time periods.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement, and from the overall relationship with
the Trust, was low. The Trustees considered other benefits that the Manager and
its affiliates receive from the relationship with the Trust, including benefits
that NYLIFE Distributors and MainStay Shareholder Services receive in exchange
for services they provide to the Funds, and certain benefits from soft dollar
arrangements. The Trustees acknowledged certain benefits to the reputation of
the Manager and the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the

                                                    www.mainstayfunds.com     27


Fund's assets, or the assets of the Trust overall, increase. The Trustees noted,
in particular, the plans of the Manager and its affiliates for marketing and
distributing the shares of the various series of the Trust. They noted the
Manager's willingness to implement a contractual breakpoint that would reduce
the Fund's management fee at asset levels above the breakpoint, and the fact
that the breakpoint was intended to provide that shareholders would share in
benefits from economies of scale obtained through the growth in the Fund's
assets. The Trustees noted that the Fund's assets had decreased in recent years
and had not yet reached the level at which the breakpoint would reduce the
Fund's management fee rate. The Trustees reviewed information about the
potential effect of asset growth on Fund expenses, the difficulty of forecasting
its effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other registered fund clients of the Manager and Subadvisor having investment
strategies similar to that of the Fund, and took account of explanations and
other information relating to the fees and expenses of those other funds and
accounts. The Trustees considered the current and proposed contractual and net
management fees, its anticipated gross and net expense ratio, and various
components of the expense ratio, in comparison to other funds in comparison
groupings. The Trustees generally acknowledged the historical relationships
among the Manager, the Subadvisor and the Trust and the likely difficulties in
implementing an alternative to the investment management arrangement between the
Trust and the Manager. The Trustees noted the Manager's agreement to continue to
waive a certain portion of its management fee and maintain the existing
contractual limitation on the Fund's net expenses.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Prior to 9/1/98 (for Class C
shares) and 12/31/03 (for Class I shares), performance for Class C and Class I
shares includes the historical performance of Class B shares adjusted to reflect
the applicable sales charge (or CDSC), fees, estimated expenses and fee
waivers/expense limitations of Class C and Class I shares upon initial offer.
Unadjusted, the performance shown for the newer classes of shares might have

 6 MainStay High Yield Corporate Bond Fund


COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY HIGH YIELD CORPORATE BOND
FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager J. Matthew Philo, CFA, of MacKay Shields
LLC

HOW DID MAINSTAY HIGH YIELD CORPORATE BOND FUND PERFORM RELATIVE TO ITS PEERS
AND ITS BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay High Yield Corporate Bond Fund returned
7.41% for Class A shares, 6.46% for Class B shares and 6.63% for Class C shares
for the 12 months ended October 31, 2007. Over the same period, the Fund's Class
I shares returned 7.49%. All share classes outper-formed the 6.21% return of the
average Lipper(1) high current yield fund and underperformed the 7.70% return of
the Credit Suisse High Yield Index(2) for the 12 months ended October 31, 2007.
The Credit Suisse High Yield Index is the Fund's broad-based securities-market
index. See page 5 for Fund returns with sales charges.

WHAT FACTORS AFFECTED THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund's performance relative to the Credit Suisse High Yield Index resulted
from our bottom-up investment style, which focused on individual companies to
determine risk-group weightings in the context of historical yield spreads.(3)
Throughout the reporting period, the Fund was underweight higher-risk bonds
because we felt that they provided insufficient compensation for the additional
risks the securities entailed. Our positioning detracted from relative results,
however, since the lowest-quality portion of the high-yield market outperformed
higher-quality high-yield bonds.

High-yield bonds reflect risks and rewards that are similar to those of
equities. As a result, traditional fixed-income strategies such as yield-curve
positioning, maturity structure and duration management are not the focal point
of our investment process.

While high-yield corporate bond holdings constitute the majority of the Fund's
holdings, the Fund usually maintains a modest weighting in common equities.
Although volatile, the trend for U.S. stocks was generally higher during the
12-month reporting period.

HOW DID YOU POSITION THE FUND FROM AN INDUSTRY PERSPECTIVE?

During the reporting period, we added to the Fund's exposure in health care and
energy. In the energy sector, the electric utility industry was among the larger
weightings in the Fund. During the reporting period, subprime-mortgage problems
spilled into other credit markets and the high-yield market in particular. By
the end of October, spreads were wider than at the beginning of the reporting
period, and relative values had improved. Late in the report-ing period, we
reduced the Fund's overall cash posi-tion to take advantage of wider spreads.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

We added to or established meaningful positions in the fixed-income securities
of Community Health Systems, Reliant Energy and TXU Electric Delivery. We
reduced or eliminated significant positions in the fixed-income securities of
Chiquita Brands International, GMAC and Jean Coutu Group.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

The Fund's weightings are a result of our bottom-up securities selection
process. As of October 31, 2007, the Fund was overweight relative to the Credit
Suisse High Yield Index in health care and energy and underweight in consumer
discretionary, including home builders and retailers.


High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher- quality debt securities
and may be subject to greater price volatility. Foreign securities may be
subject to greater risks than U.S. investments, including currency fluctuations,
less-liquid trading markets, greater price volatility, political and economic
instability, less publicly available information, and changes in tax or currency
laws or monetary policy. These risks are likely to be greater in emerging
markets than in developed markets. The Fund may experience a portfolio turnover
rate of more than 100% and may generate taxable short-term capital gains. Funds
that invest in bonds are subject to credit, inflation and interest-rate risk and
can lose principal value when interest rates rise.

3. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The term may also refer to the difference in yield between two specific
   securities or types of securities at a given time.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay High
Yield Corporate Bond Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. Class I shares commenced on January 2, 2004.
Class A shares are offered at net asset value per share plus an initial sales
charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within up to six years of purchase of Class B
shares and a 1% contingent deferred sales charge may be imposed on redemptions
made within one year of purchase of Class C shares. Class I shares are not
subject to a sales charge. As approved by the Board of Trustees in 1997, Class B
shares convert to Class A shares eight years after the date they were purchased.
The four classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A shares under a distribution plan pursuant to Rule 12b-1 under
the 1940 Act. Class I shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek maximum current income through
investment in a diversified portfolio of high yield debt securities. Capital
appreciation is a secondary objective.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium--a high interest rate or yield--because of the increased risk of
loss. These securities can also be subject to greater price volatility.

The Fund also invests in foreign securities, which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business.

Equity securities are valued at the latest quoted sales prices as of the close
of trading on the New York Stock Exchange on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in mutual funds are valued at their net asset value as of the close
of the New York Stock Exchange on the date of valuation.

Loans are valued at the average of bid quotations obtained from a pricing
service. The Trust has engaged an independent pricing service to provide market
value quotations from dealers in loans. As of October 31, 2007, 100% of total
investments in loans were valued based on prices from such services.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost. Loans are
valued at the average of bid quotations obtained from a pricing service. The
Company has engaged an independent pricing service to provide market value
quotations from dealers in loans. As of October 31, 2007, 100% of total
investments in loans were valued based on prices from such services.

 26 MainStay High Yield Corporate Bond Fund


Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund held securities with a value of $42,772,200 that
were valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income monthly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the constant yield method over the life of the
respective securities or, in the case of a callable security, over the period to
the first date of call. Discounts and premiums on short-term securities are
accreted and amortized, respectively, on the straight line method. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

The Fund may place a debt obligation on non-accrual status and reduce related
interest income by ceasing current accruals and writing off interest receivables
when the collection of all or a portion of interest has become doubtful based on
consistently applied procedures. A debt obligation is removed from non-accrual
status when the issuer resumes interest payments or when collectibility of
interest is reasonably assured.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 29) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

                                                      www.mainstayfunds.com   27

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(G) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate ("LIBOR").

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. For example, the Fund may be
contractually obligated to receive approval from the agent bank and/or borrower
prior to the sale of these investments.

The Fund assumes the credit risk of the borrower, the selling participant and
any other persons interpositioned between the Fund and the borrower
("intermediate participants"). In the event that the borrower, selling
participant or intermediate participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
borrower. At any point in time, up to the maturity date of the issue, the
borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts. (See Note 5 on page 30.)

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
rates last quoted by any major U.S. bank at the following dates:

(ii) purchases and sales of investment securities, income and expenses--at the
date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(I) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(J) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. The Fund may not
have the right to demand that such securities be registered. Disposal of these
securities may involve time-consuming negotiations and expenses and it may be
difficult to obtain a prompt sale at an acceptable price.

(K) REDEMPTION FEE.  The Fund imposes a 2.00% redemption fee on redemptions
(including exchanges) of Fund shares made within 60 days of their date of
purchase for any class. The redemption fee is designed to offset brokerage
commissions and other costs associated with short-term trading and is not
assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and retained by the
Fund.

(L) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations

 28 MainStay High Yield Corporate Bond Fund


will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.60% on assets up to $500 million; 0.55% on assets from
$500 million to $5 billion and 0.525% on assets in excess of $5 billion. Prior
to August 1, 2007, the Fund was contractually obligated to pay NYLIM a monthly
fee for services performed and facilities furnished at an annual rate of the
Fund's average daily net assets as follows: 0.60% on assets up to $500 million
and 0.55% on assets in excess of $500 million. For the year ended October 31,
2007, NYLIM earned fees from the Fund in the amount of $25,634,409. It was not
necessary for NYLIM to reimburse the Fund for expenses for the year ended
October 31, 2007.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENT FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters". (See Note 11 on
page 32.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $388,736. Additional payments
were made by affiliates relating to the shareholder trading matters. Further
discussion regarding those payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly
distribution fee from the Fund at an annual rate of 0.25% of the average daily
net assets of the Fund's Class A shares, which is an expense of the Class A
shares of the Fund for distribution or service activities as designated by the
Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the
Distributor a monthly distribution fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Plans provide that the
Class B and Class C shares of the Fund also incur a service fee at the annual
rate of 0.25% of the average daily net asset value of the Class B and Class C
shares of the Fund. Class I shares are not subject to a distribution or service
fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $637,611 for the year
ended October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $51,050, $1,359,216 and $79,935, respectively, for the year ended
October 31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $7,361,520.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>

Class I                              7,372,592       1.7
- ----------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(H) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $175,605.
The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $485,776 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>

 ------------------------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals, premium amortization adjustments and
partnership adjustments.

The other temporary differences are primarily due to distribution payable and
interest on defaulted securities.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income and accumulated net
realized loss on investments, arising from permanent differences; net assets at
October 31, 2007 are not affected.

 ------------------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments, paydown gain (loss), foreign currency gain (loss) and prior year
return of capital.

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $594,767,433 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

NOTE 11--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the MainStay
High Yield Corporate Bond Fund was $814,000. NYLIM has reimbursed or paid all
expenses relating to the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measure-

 32 MainStay High Yield Corporate Bond Fund


ments." This standard establishes a single authoritative definition of "fair
value", sets out a framework for measuring fair value and requires additional
disclosures about fair value measurements. SFAS No. 157 applies to fair value
measurements already required or permitted by existing standards. SFAS No. 157
is effective for financial statements issued for fiscal years beginning after
November 15, 2007 and interim periods within those fiscal years. The changes to
current generally accepted accounting principles from the application of this
Statement relate to the definition of fair value, the methods used to measure
fair value, and the expanded disclosures about fair value measurements. As of
October 31, 2007, the Fund does not believe the adoption of SFAS No. 157 will
impact the amounts reported in the Fund's financial statements. However,
additional disclosures may be required about the inputs used to develop the
measurements and the effect of certain measurements reported in the financial
statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay High Yield Corporate Bond Fund
("the Fund"), one of the funds constituting The MainStay Funds, as of October
31, 2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year period
then ended, and the financial highlights for each of the years or periods in the
four-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay High Yield Corporate Bond Fund of The MainStay Funds as of October 31,
2007, the results of its operations for the year then ended, the changes in its
net assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years or periods in the four-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's historical and
continuing outstanding investment performance record when compared over several
time periods with groupings of funds having similar investment mandates.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate
to low, and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees recognized the large asset size of the Fund relative to other
series of the Trust, and discussed the extent to which economies of scale were
projected by the Manager to be realized as the Fund's assets, or the assets of
the Trust overall, increase. The Trustees noted, in particular, the plans of the
Manager and its affiliates for marketing and distributing the shares of the
various series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints, including a new breakpoint, that would reduce the
Fund's management fee at asset levels above each breakpoint, and the fact that
the breakpoints were intended to provide that shareholders would share in
benefits from economies of scale obtained

                                                      www.mainstayfunds.com   35


through the growth in the Fund's assets. The Trustees noted that the Fund's
management fee rate had been reduced by the breakpoint schedule applicable to
the Fund. The Trustees reviewed information showing that the Fund's asset size
had decreased based in part on investment trends that appeared to focus more
heavily on other asset classes. The Trustees reviewed information about the
potential effect of asset growth on Fund expenses, the difficulty of forecasting
its effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. The
Trustees considered information about transfer agency expenses and their effect
on the Fund's overall expenses. They considered that, across the Trust (though
not every series or share class), gross transfer agency fees tended to be
relatively high and, therefore, adversely affected gross expense ratios. Noting
that the Trust historically permitted smaller investor accounts, the Trustees
considered measures that had been recently implemented that were intended to
increase the average size of shareholder accounts, including generally higher
investment minimums and small account fees, and the Trustees considered
potential benefits to the Manager and its affiliates arising from such measures.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationships among the Manager, the Subadvisor and the Trust and the
likely difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC, and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC, and have an annual 12b-1 fee of
..25%. Class R1 and R2 shares are available only through corporate-sponsored
retirement programs, which include certain minimum program requirements.

Class R3 shares are sold with no initial sales charge or CDSC, have an annual
12b-1 fee of .50%, and are available in certain individual retirement accounts
or in certain retirement plans. Performance figures reflect certain fee waivers
and/or expense limitations, without which total returns may have been lower.
These fee waivers and/or expense limitations are contractual and may be modified
or terminated only with the approval of the Board of Trustees. The Manager may
recoup the amount of certain management fee waivers or expense reimbursements
from the Fund pursuant to the contract if such action does not cause the Fund to
exceed existing expense limitations and the recoupment is made within three
years after the year in which the Manager incurred the expense. Prior to 9/1/98
(for Class C), 1/2/04 (for Class I, R1 and R2) and 4/28/06 (for Class R3),
performance for Class C, I, R1, R2 and R3 shares includes the historical
performance of Class B shares adjusted to reflect the applicable sales charge
(or CDSC), fees, estimated expenses and fee waivers/expense limitations of Class
C, I, R1, R2, and R3 shares upon initial offer. Unadjusted, the performance
shown for the newer classes of shares might have been lower.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY INTERNATIONAL EQUITY FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Rupal J. Bhansali of MacKay Shields LLC

HOW DID MAINSTAY INTERNATIONAL EQUITY FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay International Equity Fund returned 16.30%
for Class A shares, 15.48% for Class B shares and 15.49% for Class C shares for
the 12 months ended October 31, 2007. Over the same period, the Fund's Class I
shares returned 16.96%, Class R1 shares returned 16.88%, Class R2 shares
returned 16.49% and Class R3 shares returned 16.35%. All share classes
underperformed the 27.22% return of the average Lipper(1) international
multi-cap core fund and the 24.91% return of the MSCI EAFE(R) Index(2) for the
12 months ended October 31, 2007. The MSCI EAFE(R) Index is the Fund's
broad-based securities-market index. See page 5 for Fund returns with sales
charges.

WHAT FACTORS AFFECTED THE FUND'S RELATIVE PERFORMANCE?

We remained focused on the analysis of individual business models and sought to
invest in quality companies. Our bottom-up security selection process is based
on reasonable valuations rather than market perceptions. During the reporting
period, this approach pointed the Fund to companies in the transportation, media
and technology hardware & equipment industry groups and away from companies in
capital goods, materials and banks.

DURING THE REPORTING PERIOD, WHICH INDUSTRY GROUPS WERE THE STRONGEST
CONTRIBUTORS TO THE FUND'S RELATIVE PERFORMANCE AND WHICH INDUSTRY GROUPS WERE
WEAK CONTRIBUTORS?

Banks and diversified financials made the largest contribution to the Fund's
relative performance during the reporting period because of security selection
and underweight allocations. Toward the end of the reporting period, the
financials sector as a whole declined, as credit issues in the mortgage market
became more apparent. The retailing industry group was also a strong contributor
to the Fund's performance. Esprit, a Hong Kong-based global clothing retailer,
performed well as its growth prospects in Europe improved.

Exposure to the technology hardware & equipment industry group detracted from
the Fund's relative results, primarily because of an overweight position in
Ericsson, a Sweden-based wireless equipment company. Late in the reporting
period, Ericsson warned that earnings would miss target levels, and the
company's share price declined.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL FUND HOLDINGS DID PARTICULARLY
WELL AND WHICH HOLDINGS WERE WEAK?

Ryanair, a low-cost airline headquartered in Ireland, was among the strongest
positive contributors to the Fund's performance. The company raised fares and
ancillary revenues to offset high jet-fuel prices. Tesco, the U.K.'s largest
food retailer, saw its shares advance on better-than-anticipated progress in the
company's U.S. expansion. Nestle, the world's largest food manufacturer, saw its
major restructuring efforts begin to bear fruit with expanding profit margins
and growing revenues.

The Fund's weakest holding during the reporting period was Italian media company
MediaSet, which has been highly profitable but underperformed when weakness in
the Italian advertising market led to earnings downgrades. The Fund continues to
hold the stock. Another weak holding was Ireland-based C&C Group, a major
beverage company with a unique franchise in the cider industry. The company's
stock declined after the company missed earnings expectations following a wet
and cool summer. Wireless equipment supplier Ericsson also detracted from Fund
results.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

We established new positions in Japan's NTT DoCoMo and Italy's Telecom Italia as
the outlook for cash flow and earnings in the telecommunication services sector
improved. When Puma's share price dropped we found the valuations compelling and
increased the Fund's position.

We sold stocks that we felt had reached their intrinsic value and had become
stretched on a valuation basis. Japanese pharmaceutical company Takeda
Pharmaceutical, Canadian software company Cognos and U.K.-based Royal Bank of
Scotland all fit this description. We also eliminated the Fund's position in
HongKong Electric in advance of a


Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund. The Fund may experience a
portfolio turnover rate of more than 100% and may generate taxable short-term
capital gains.

challenging regulatory review set for the end of 2007.

HOW WAS THE FUND POSITIONED RELATIVE TO THE MSCI EAFE(R) INDEX AT THE END OF THE
REPORTING PERIOD?

As of October 31, 2007, the Fund held significantly overweight positions
relative to the MSCI EAFE(R) Index in transportation, technology hardware &
equipment, media and food & staples retailing and a more modestly overweight
position in health care. On the same date, the Fund was underweight relative to
the Index in banks, capital goods and materials. The Fund held market-weight
positions in utilities and energy. The overweight position in media and a lack
of exposure to materials hurt the Fund's relative results during the reporting
period.

During the reporting period, we found fewer compelling investment opportunities
in Japan than we did in Europe and the rest of Asia. As a result, the Fund
maintained its underweight position in Japan.

are an integral part of, and should be read in conjunction with, the financial
statements.


NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay
International Equity Fund (the "Fund"), a diversified fund.

The Fund currently offers seven classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on September 13, 1994. Class C shares
commenced on September 1, 1998. Class I shares, Class R1 shares and Class R2
shares commenced on January 2, 2004. Class R3 shares commenced on April 28,
2006. Class A shares are offered at net asset value per share plus an initial
sales charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within up to six years of purchase of Class B
shares and a 1% contingent deferred sales charge may be imposed on redemptions
made within one year of purchase of Class C shares. Class I, Class R1, Class R2
and Class R3 shares are not subject to a sales charge. As approved by the Board
of Trustees in 1997, Class B shares convert to Class A shares eight years after
the date they were purchased. The seven classes of shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions except that Class B and Class C shares are subject
to higher distribution fee rates than Class A, Class R2 and Class R3 shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I and
Class R1 shares are not subject to a distribution or service fee. Class R1,
Class R2 and Class R3 shares are authorized to pay to New York Life Investment
Management LLC, its affiliates, or third-party service providers, as
compensation for services rendered to shareholders of Class R1, Class R2 or
Class R3 shares, a shareholder service fee.

The Fund's investment objective is to provide long-term growth of capital
commensurate with an acceptable level of risk by investing in a portfolio
consisting primarily of non-U.S. equity securities. Current income is a
secondary objective.

The Fund invests in foreign securities, which carry certain risks that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Options
contracts are valued at the last posted settlement price on the market where
such options are principally traded. Investments in mutual funds are valued at
their net asset value as of the close of the New York Stock Exchange on the date
of valuation. Foreign currency forward contracts are valued at their fair market
values determined on the basis of the mean between the last current bid and ask
prices based on dealer or exchange quotations.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

where the trading on that security's principal market is temporarily closed at a
time when, under normal conditions, it would be open. At October 31, 2007, the
Fund held securities with a value of $97,638 that were valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the constant yield method over the life of the
respective securities or, in the case of a callable security, over the period to
the first date of call. Discounts and premiums on short-term securities are
accreted and amortized, respectively, on the straight line method. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 26) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are canceled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the price of the underlying security or foreign currency
increase. By writing a covered put option, the Fund, in exchange for the
premium, accepts the risk of a decline in the market value of the underlying
security or foreign currency below the exercise price. A call option may be
covered by the call writer's owning the underlying security throughout the
option period. A call option may

 24   MainStay International Equity Fund


also be covered by the call writer's maintaining liquid assets valued at greater
than the exercise price of the call written. When writing a covered call option,
the Fund, in return for the premium on the option, gives up the opportunity to
profit from a price increase in the underlying securities above the exercise
price, but, as long as the obligation as the writer continues, has retained the
risk of loss should the price of the underlying security decline. After writing
a put option, the Fund may incur a loss equal to the difference between the
exercise price of the option and the sum of the market value of the underlying
security plus the premium received from the sale of the option.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option. (See Note 5 on page 28.)

(H) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. (See Note 5 on page 28.)

(I) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
rates last quoted by any major U.S. bank at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(J) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(K) REDEMPTION FEE.  The Fund imposes a 2.00% redemption fee on redemptions
(including exchanges) of Fund shares made within 60 days of their date of
purchase for any class. The redemption fee is designed to offset brokerage
commissions and other costs associated with short-term trading and is not
assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and retained by the
Fund.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(L) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.90% on assets up to $500 million and 0.85% on assets in
excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.60%; Class B, 2.35%; Class C, 2.35%; Class I, 1.03%;
Class R1, 1.13%; Class R2, 1.38% and Class R3, 1.63%. This expense limitation
may be modified or terminated only with the approval of the Board of Trustees.
NYLIM may recoup the amount of any management fee waivers or expense
reimbursements from the Fund pursuant to the agreement if such action does not
cause the Fund to exceed existing expense limitations and the recoupment is made
within three years after the year in which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $7,496,336 and recouped $176,299.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
                       OCTOBER 31,
               2009                  TOTAL
                           
             $183,002               $183,002
       -------------------------------------------
</Table>

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.60% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 10 on
page 31.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $23,939. Additional payments were
made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, Class R2 and Class R3 shares, has
adopted

 26   MainStay International Equity Fund


distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act.

Pursuant to the Class A and Class R2 Plans, the Distributor receives a monthly
distribution fee from the Fund at an annual rate of 0.25% of the average daily
net assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly distribution fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
and Class C shares of the Fund. Pursuant to the Class R3 Plan, the Distributor
receives a monthly distribution fee from the Fund at the annual rate of 0.50% of
the average daily net assets of the Fund's Class R3 shares, which is an expense
of the Class R3 shares of the Fund for distribution or service activities as
designated by the Distributor. Class I and Class R1 shares are not subject to a
distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

In accordance with the Shareholder Services Plans for the Class R1, Class R2 and
Class R3 shares, the Manager has agreed to provide, through its affiliates or
independent third parties, various shareholder and administrative support
services to shareholders of the Class R1, Class R2 and Class R3 shares. For its
services, the Manager is entitled to a Shareholder Service Fee accrued daily and
paid monthly at an annual rate of 0.10% of the average daily net assets
attributable to the Class R1, Class R2 and Class R3 shares.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $94,608 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5,046, $89,141 and $9,777, respectively, for the year ended October
31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $975,286.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>

(H) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $32,381.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $111,917 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals and straddle loss deferrals.

arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the MainStay
International Equity Fund was $772,000. NYLIM has reimbursed or paid all
expenses relating to the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay International Equity Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years or periods in the
two-year period then ended, and the financial highlights for each of the years
or periods in the four-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay International Equity Fund of The MainStay Funds as of October 31, 2007,
the results of its operations for the year then ended, the changes in its net
assets for each of the years or periods in the two-year period then ended, and
the financial highlights for each of the years or periods in the four-year
period then ended, in conformity with U.S. generally accepted accounting
principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's outstanding investment
performance over the past year and the Fund's satisfactory longer term
performance.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate
to low, and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at asset
levels above the breakpoint, and the fact that the

                                                    www.mainstayfunds.com     33


breakpoint was intended to provide that shareholders would share in benefits
from economies of scale obtained through the growth in the Fund's assets. The
Trustees noted that, due to the growth of the Fund's assets during the past two
years, the Fund's management fee rate had been reduced by the breakpoint
schedule applicable to the Fund. The Trustees reviewed information about the
potential effect of asset growth on Fund expenses, the difficulty of forecasting
its effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees took account of the Manager's willingness to maintain the management
fee waiver and expense limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end October 31, 2007 as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $36,851,040.

In accordance with federal tax law, the Fund elects to provide each shareholder
with their portion of the Fund's foreign faxes paid and the income sourced from
foreign countries. Accordingly, the Fund hereby makes the following designations
regarding its fiscal year ended October 31, 2007:

- -- the total amount of taxes paid to foreign countries was $2,357,630

- -- the total amount of income sourced from foreign countries was $25,188,855

As required by federal tax law rules, shareholders will receive notification of
their proportionate share of foreign taxes paid and foreign sourced income for
the 2007 calendar year with form 1099-DIV, which will be mailed during January

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of
..25%. Class R1 and Class R2 shares are only available through
corporate-sponsored retirement programs, which include certain minimum program
requirements. Class R3

On 4/1/05, FMI Winslow Growth Fund was reorganized into Class A shares of the
Fund. Effective 6/29/05, MainStay Blue Chip Growth Fund, which had assets of
$234.1 million, also merged into the Fund, which had assets of $16.5 million.
Performance for the Fund includes the performance history of FMI Winslow Growth
Fund from inception (7/1/95) through 3/31/05, during which time FMI Winslow
Growth Fund's asset size generally was in the range of $4 million to $52
million. Performance history shown for the Fund through 3/31/05, therefore,
reflects performance of a much smaller portfolio than the current Fund.
Performance shown may not be indicative of what performance would have been had
the portfolio been larger.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY LARGE CAP GROWTH FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.
Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Clark J. Winslow, Justin H. Kelly, CFA,
and R. Bart Wear, CFA, of Winslow Capital Management, Inc.

HOW DID MAINSTAY LARGE CAP GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12-MONTH REPORTING PERIOD?

Excluding all sales charges, MainStay Large Cap Growth Fund returned 26.20% for
Class A shares, 25.48% for Class B shares and 25.30% for Class C shares for the
12 months ended October 31, 2007. Over the same period, the Fund returned 27.16%
for Class I shares, 26.92% for Class R1 shares, 26.71% for Class R2 shares and
26.42% for Class R3 shares. All share classes outperformed the 21.72% return of
the average Lipper(1) large-cap growth fund and the 19.23% return of the Russell
1000(R) Growth Index(2) for the 12 months ended October 31, 2007. The Russell
1000(R) Growth Index is the Fund's broad-based securities-market index. See page
5 for Fund returns with sales charges.

WHAT ACCOUNTED FOR THE FUND'S RELATIVE PERFORMANCE?

The Fund's relative performance resulted primarily from favorable stock
selection and overweight positions in telecommunication services, information
technology and health care.

WHICH SECTORS WERE AMONG THE FUND'S STRONGEST PERFORMERS FOR THE 12 MONTHS ENDED
OCTOBER 31, 2007, AND WHICH SECTORS WERE THE WEAKEST?

Materials was the Fund's strongest sector on an absolute basis.
Telecommunication services was the second-best-performing sector, with
performance driven by the growing use of cell phones worldwide. Energy was the
Fund's third-strongest sector, boosted by the sharp increase in the price of
oil.

The Fund's only negative sector return came from consumer discretionary. The
sector suffered from the effects of housing issues and high energy prices.
Although consumer staples and financials generated positive absolute returns,
both sectors underper-formed the Russell 1000(R) Growth Index.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS WERE STRONG PERFORMERS AND
WHICH STOCKS WERE WEAK?

A position in Research In Motion provided the largest positive contribution to
the Fund's performance. The stock advanced on strong acceptance of the
BlackBerry(R), an integrated wireless solution. The BlackBerry platform and
devices contributed to sharp increases in the company's earnings. Apple
experienced favorable demand for virtually all of its products, and the
company's rising share price enhanced Fund results. America Movil, which is one
of the Fund's largest holdings, saw its share price rise sharply because of
surging cell phone use in Latin America, where the company is the largest
service provider.

The greatest detractor from the Fund's absolute performance was Merrill Lynch,
which suffered from large mortgage-related losses. Fortunately, the negative
results had a fairly modest impact on the Fund's performance. Comverse
Technology and Akamai Technologies also generated small declines as fundamentals
weakened.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

The Fund established a position in Intuitive Surgical. The company's shares rose
dramatically from initial purchase through the end of October, driven by strong
acceptance of the company's robotic surgery tools. We also initiated a position
in Medco Health Solutions to take advantage of strong earnings growth potential
as this pharmacy benefits manager increased its penetration in the drug-delivery
market. In early 2007, we established a major position in Southwestern Energy,
believing that the company would be successful in materially increasing its
natural gas production. This view proved correct, and the company's stock price
advanced.

Poor performance in Merrill Lynch, Comverse Technology and Akamai Technologies
led us to eliminate each of these stocks during the reporting period.

WERE THERE ANY CHANGES IN THE FUND'S POSITIONING DURING THE REPORTING PERIOD?

Weighting changes are primarily a residual of the Fund's stock-specific
investment approach. During the reporting period, we increased the Fund's
position in telecommunication services to a substantial overweight relative to
the Russell 1000(R) Growth Index, seeking to benefit from global growth in cell
phone use. We also increased the Fund's exposure to the information technology
sector from slightly underweight relative to the Russell 1000(R) Growth Index to
moderately overweight. We added exposure to technology companies with
significant international business, which has been growing faster than business
in the United States.

   Index.

 10   MainStay Large Cap Growth Fund


The housing situation and higher energy prices led us to reduce the Fund's
already underweight positions in the consumer discretionary and consumer staples
sectors.

As of October 31, 2007, the Fund held overweight positions relative to the
Russell 1000(R) Growth Index in America Movil, Southwestern Energy and Medco
Health Solutions. On the same date, the Fund held no individual stock positions

that were underweight relative to the benchmark.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Large Cap
Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers seven classes of shares. Class A shares, Class B
shares, Class C shares, Class I shares, Class R1 shares and Class R2 shares
commenced on March 31, 2005. Distribution of Class R3 shares commenced on April
28, 2006. Class A shares are offered at net asset value per share plus an
initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Class A shares, but a contingent
deferred sales charge is imposed on certain redemptions of such shares within
one year of the date of purchase. Class B shares and Class C shares are offered
without an initial sales charge, although a declining contingent deferred sales
charge may be imposed on redemptions made within up to six years of purchase of
Class B shares and a 1% contingent deferred sales charge may be imposed on
redemptions made within one year of purchase of Class C shares. Class I, Class
R1, Class R2 and Class R3 shares are not subject to a sales charge. As approved
by the Board of Trustees in 1997, Class B shares convert to Class A shares eight
years after the date they were purchased. The seven classes of shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that Class B and Class C
shares are subject to higher distribution fee rates than Class A, Class R2 and
Class R3 shares under a distribution plan pursuant to Rule 12b-1 under the 1940
Act. Class I and Class R1 shares are not subject to a distribution or service
fee. Class R1, Class R2 and Class R3 shares are authorized to pay to New York
Life Investment Management LLC, its affiliates, or third-party service
providers, as compensation for services rendered to shareholders of Class R1,
Class R2 or Class R3 shares, a shareholder service fee.

The Fund's investment objective is to seek long-term growth of capital.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Investments
in mutual funds are valued at their net asset value as of the close of the New
York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are

 20   MainStay Large Cap Growth Fund


reclassified amongst undistributed net investment income, accumulated net
realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 22) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. Winslow Capital
Management, Inc. (the "Subadvisor"), is responsible for the day-to-day portfolio
management of the Fund. Pursuant to the terms of a Subadvisory Agreement between
NYLIM and the Subadvisor, NYLIM pays for the services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.80% on assets up to $250 million, 0.75% on assets from
$250 million up to $500 million, 0.725% on assets from $500 million up to $750
million, 0.70% on assets from $750 million up to $2.0 billion, 0.65% on assets
from $2.0 billion up to $3.0 billion and 0.60% on assets in excess of $3.0
billion. The Manager has contractually agreed to waive a portion of its
management fee so that the management fee does not exceed 0.75% on assets up to
$250 million, which is not recoupable.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.40%; Class B, 2.15%; Class C, 2.15%; Class I, 0.75%;
Class R1, 0.85%; Class R2, 1.10% and Class R3, 1.35%. This expense limitation
may be modified or terminated only

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

with the approval of the Board of Trustees. NYLIM may recoup the amount of any
management fee waivers or expense reimbursements from the Fund pursuant to the
agreement if such action does not cause the Fund to exceed existing expense
limitations and the recoupment is made within three years after the year in
which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $6,080,582 and waived its fees in the amount of $838,664 of which
$713,664 is recoupable.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
                       OCTOBER 31,
        2008*             2009         2010       TOTAL

- ----------------------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.40% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, Class R2 and Class R3 shares, has
adopted distribution plans (the "Plans") in accordance with the provisions of
Rule 12b-1 under the 1940 Act.

Pursuant to the Class A and Class R2 Plans, the Distributor receives a monthly
distribution fee from the Fund at an annual rate of 0.25% of the average daily
net assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly distribution fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
and Class C shares of the Fund. Pursuant to the Class R3 Plan, the Distributor
receives a monthly distribution fee from the Fund at the annual rate of 0.50% of
the average daily net assets of the Fund's Class R3 shares, which is an expense
of the Class R3 shares of the Fund for distribution or service activities as
designated by the Distributor. Class I and Class R1 shares are not subject to a
distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

In accordance with the Shareholder Services Plans for the Class R1, Class R2 and
Class R3 shares, the Manager has agreed to provide, through its affiliates or
independent third parties, various shareholder and administrative support
services to shareholders of the Class R1, Class R2 and Class R3 shares. For its
services, the Manager is entitled to a Shareholder Service Fee accrued daily and
paid monthly at an annual rate of 0.10% of the average daily net assets
attributable to the Class R1, Class R2 and Class R3 shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $98,354 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $2,876, $170,718 and $10,515, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $1,720,985.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000

 22   MainStay Large Cap Growth Fund


are charged an annual per account fee of $20 (assessed semi-annually).

The reclassifications for the Fund are primarily due to net operating losses and
foreign currency reclass.

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $132,965,471 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

NOTE 9--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Large Cap Growth Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2007, and the related statements of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year period
then ended, and the financial highlights for each of the years or periods in the
two-year period then ended, the four-month period ended October 31, 2005, and
the year ended June 30, 2005. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights for the years presented through
June 30, 2004, were audited by other auditors, whose report dated August 4,
2004, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Large Cap Growth Fund of The MainStay Funds as of October 31, 2007, and
the results of its operations for the year then ended, the changes in its net
assets for the two-year period then ended, and the financial highlights for the
two-year period then ended, the four-month period ended October 31, 2005, and
the year ended June 30, 2005, in conformity with U.S. generally accepted
accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and Winslow Capital Management, Inc.
(the "Subadvisor") (each an "Agreement") at a meeting held on May 22 and 23,
2007. In connection with the approval of each Agreement, the Trustees reviewed a
significant amount of a wide variety of information that they had requested and
received from the Manager and the Subadvisor, and data and analysis from an
outside data provider and a third party consultant. The Trustees considered
various industry trends and regulatory developments in their deliberations. In
considering approval of each Agreement, and in evaluating the fairness of the
compensation to be paid by the Fund, the Trustees met both as a full Board and
in executive session with no Interested Trustee present, in advance of the
meeting at which the Agreements were approved, and they considered a number of
factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager, has
provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's excellent performance
under the Subadvisor over most time periods and generally favorably
risk-adjusted returns since FMI Winslow Growth Fund was reorganized with and
into the Fund in 2004.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates and the subadvisory fee payments
made by the Manager to the Subadvisor. The Trustees were provided information
that indicated that the profitability to the Manager and its affiliates from the
Management Agreement, and from the overall relationship with the Trust, was low.
The Trustees considered other benefits that the Manager and its affiliates
receive from the relationship with the Trust, including benefits that NYLIFE
Distributors and MainStay Shareholder Services receive in exchange for services
they provide to the Funds, and certain benefits from soft dollar arrangements.
The Trustees acknowledged certain benefits to the reputation of the Manager and
the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Subadvisor, including that the program was designed to
reward providing favorable long-term results for clients. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

                                                    www.mainstayfunds.com     27


The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints that would reduce the Fund's management fee at asset
levels above the breakpoints, and the fact that the breakpoints were intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund's management fee rate had been reduced by the breakpoint schedule
applicable to the Fund. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager or Subadvisor, including other registered funds and
separate institutional accounts having investment strategies similar to that of
the Fund, and took account of explanations and other information relating to the
fees and expenses of those other funds and accounts. The Trustees considered the
current and proposed contractual and net management fees, its anticipated gross
and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees reviewed
information relating to the amount of the management fee retained by the Manager
and the amount paid by the Manager to the Subadvisor. The Trustees generally
acknowledged the historical relationships among the Manager and the Trust and
the likely difficulties in implementing an alternative to the investment
management arrangement between the Manager and the Trust. The Trustees took
account of the Manager's willingness to continue to waive a certain portion of
its management fee and maintain the existing contractual limitation on the
Fund's net expenses and the fact that the fee waiver and expense limitation did
not reduce the level of the subadvisory fee payable by the Manager to the
Subadvisor.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MAP FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.
Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Michael J. Mullarkey, Roger Lob and
Christopher Mullarkey of Markston International LLC and by portfolio managers
Jerrold K. Senser, CFA, and Thomas R. Wenzel, CFA, of Institutional Capital LLC

HOW DID MAINSTAY MAP FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK DURING
THE 12-MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay MAP Fund returned 16.61% for Class A
shares, 15.73% for Class B shares and 15.73% for Class C shares for the 12
months ended October 31, 2007. Over the same period, the Fund's Class I shares
returned 16.99%, Class R1 returned 16.89%, Class R2 shares returned 16.61% and
Class R3 shares returned 16.37%. With the exception of Class B and Class C
shares, all share classes outperformed the 16.05% return of the average
Lipper(1) multi-cap core fund for the 12-month reporting period. All share
classes outperformed the 14.53% return of the Russell 3000(R) Index,(2) the
Fund's broad-based securities-market index, for the 12 months ended October 31,
2007. See page 5 for Fund returns with sales charges.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE GREATEST POSITIVE
CONTRIBUTIONS TO PERFORMANCE IN YOUR PORTION OF THE FUND AND WHICH SECTORS WERE
THE GREATEST DETRACTORS?

Markston International:
In our portion of the Fund, agriculture-related stocks performed extremely well
on an absolute basis, supported by record domestic corn plantings and strong
worldwide demand for fertilizer. The Fund's energy stocks also generated strong
absolute performance as a result of record oil prices. Finally, some of our
information technology holdings performed well on an absolute basis, as online
business activity continued to grow. Better-than-expected growth rates for
personal computers helped computer hardware holdings in our portion of the Fund.
The weakest-performing sector in our portion of the Fund was financials, which
suffered from the subprime-mortgage crisis. Select biotechnology holdings
weakened because of concerns over Medicare reimbursement and tighter Food and
Drug Administration controls.

ICAP:
Relative to the S&P 500(R) Index,(3) energy, consumer staples and materials were
the top-performing sectors in our portion of the Fund. Information technology,
utilities and health care were our weakest sectors relative to the S&P 500(R)
Index.

DURING THE REPORTING PERIOD, WHICH STOCKS WERE STRONG CONTRIBUTORS TO
PERFORMANCE IN YOUR PORTION OF THE FUND AND WHICH STOCKS DETRACTED?

Markston International:
In our portion of the Fund, Aetna benefited from higher insurance-policy prices
and a very efficient growth plan. Monsanto advanced when farmers increased their
use of the company's modified seeds. MetLife benefited from successful
disposition of noncore assets and the company's acquisition of Travelers'
annuity business. Amgen detracted from performance when two of its
pharmaceutical products, Aranesp and Epogen, faced concerns about side effects,
regulatory issues and insurance troubles. Citigroup and Banco Popular both
suffered from the fallout in the subprime-mortgage market.

ICAP:
In our portion of the Fund, Hess, Occidental Petroleum and Textron were the
strongest contributors to absolute performance. Holdings that detracted the most
from absolute performance were Office Depot, Novartis AG and Citigroup. We
eliminated our position in Office Depot during the third quarter of 2007.


The principal risk of investing in value stocks is that they may never reach
what the portfolio manager believes is their full value or they may even go down
in value. Mid-capitalization companies are generally less established and their
stocks may be more volatile and less liquid than the securities of larger
companies. Stocks of small companies may be subject to higher price volatility,
significantly lower trading volumes, and greater spreads between bid and ask
prices than stocks of larger companies. Small companies may be more vulnerable
to adverse business or market developments than mid- or large-capitalization
companies. Funds that invest in bonds are subject to credit, inflation and
interest-rate risk and can lose principal value when interest rates rise.
Issuers of convertible securities may not be as financially strong as issuers of
securities with higher credit ratings and may be more vulnerable to changes in
the economy. If an issuer stops making interest payments, principal payments or
both on its convertible securities, these securities may become worthless and
the Fund could lose its entire investment in them.

 10   MainStay MAP Fund


WERE THERE ANY SIGNIFICANT PURCHASES OR SALES IN YOUR PORTION OF THE FUND DURING
THE REPORTING PERIOD?

Markston International:
During the reporting period, we initiated a position in VeriSign, whose major
restructuring effort was led by a brand new management team and new group of
directors. We also invested in U.S. Bancorp, a company that offered a very
attractive dividend yield when the Federal Reserve was moving to lower interest
rates. We purchased Leucadia for our portion of the Fund when we felt the share
price was close to the company's underlying book value. We eliminated positions
in Ohio Casualty and Kinder Morgan when the companies were acquired at
attractive premiums. We reduced our position in Harris Corp. after its stock had
appreciated significantly.

ICAP:
During the reporting period, we introduced Coca-Cola to our portion of the Fund
because we expected management to alleviate several problems that had plagued
the company in recent years. We purchased Cisco Systems expecting that new
product growth would sustain double-digit revenue growth for the company. Among
the stocks we eliminated during the reporting period were Schlumberger and
McDonald's, both of which had reached our price targets.

DID THE SECTOR WEIGHTINGS IN YOUR PORTION OF THE FUND CHANGE DURING THE
REPORTING PERIOD?

Markston International:
During the reporting period, our portion of the Fund reduced exposure to the
industrials sector relative to the Russell 3000(R) Index. Although we added to
our weightings in information technology and consumer discretionary, our portion
of the Fund remained underweight relative to the Russell 3000(R) Index in both
of these sectors. As of October 31, 2007, our portion of the Fund was
underweight in consumer discretionary and consumer staples and overweight in
financials.

ICAP:
In our portion of the Fund, weightings relative to the S&P 500(R) Index
increased substantially in telecommunication services and information technology
and decreased significantly in utilities, energy and financials.

As of October 31, 2007, materials and telecommunication services were the most
heavily overweight positions relative to the S&P 500(R) Index. Over the course
of the reporting period, this positioning had a positive impact on performance.
Positioning in consumer discretionary and energy--our two most underweight
sectors relative to the S&P 500(R) at the end of October--had a positive impact
on performance. Utilities, which had a relatively neutral impact on relative
performance, was also underweight as of October 31, 2007.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay MAP Fund
(the "Fund"), a diversified fund.

The Fund currently offers seven classes of shares. Class A shares, Class B
shares, Class C shares and Class I shares commenced on June 9, 1999. Class R1
shares and Class R2 shares commenced on January 2, 2004. Class R3 shares
commenced on April 28, 2006. Class A shares are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within up to
six years of purchase of Class B shares and a 1% contingent deferred sales
charge may be imposed on redemptions made within one year of purchase of Class C
shares. Class I, Class R1, Class R2 and Class R3 shares are not subject to a
sales charge. As approved by the Board of Trustees in 1997, Class B shares
convert to Class A shares eight years after the date they were purchased. The
seven classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A, Class R2 and Class R3 shares under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I and Class R1 shares are not
subject to a distribution or service fee. Class R1, Class R2 and Class R3 shares
are authorized to pay to New York Life Investment Management LLC, its
affiliates, or third-party service providers, as compensation for services
rendered to shareholders of Class R1, Class R2 or Class R3 shares, a shareholder
service fee.

The Fund's investment objective is to seek long-term appreciation of capital.
The Fund also seeks to earn income, but this is a secondary objective.

The Fund invests in foreign securities, which carry certain risks that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business.

Equity securities are valued at the latest quoted sales prices as of the close
of trading on the New York Stock Exchange on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in mutual funds are valued at their net asset value as of the close
of the New York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Board of Trustees to represent fair value.
Equity and non-equity securities which may be valued in this manner include, but
are not limited to: a security the trading for which has been halted or
suspended; a debt security that has recently gone into default and for which
there is not current market quotation; a security of an issuer that has entered
into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund held

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

securities with a value of $763,168 that were valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the constant yield method over the life of the
respective securities or, in the case of a callable security, over the period to
the first date of call. Discounts and premiums on short-term securities are
accreted and amortized, respectively, on the straight line method. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 25) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred.

Based on experience, management is of the view that the risk of loss in
connection with these potential indemnification obligations is remote. However,
there can be no assurance that material liabilities related to such obligations
will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. Markston International LLC
and Institutional Capital Corp. (the "Subadvisors") each act as subadvisors to
the Fund and manage a portion of the Fund's assets, as designated by NYLIM from
time to time, subject to the oversight of NYLIM. Each Subadvisor is responsible
for the day-to-day portfolio management of the Fund with respect to its
allocated portion of the Fund's assets. Pursuant to the terms of the Subadvisory
Agreements between NYLIM and the Subadvisors, NYLIM pays for the services of the
Subadvisors.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.75% on assets up to $1.0 billion and 0.70% on assets in
excess of $1.0 billion.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.35%; Class B, 2.10%; Class C, 2.10%; Class I, 0.98%;
Class R1, 1.08%; Class R2, 1.33% and Class R3, 1.58%. This expense limitation
may be modified or terminated only with the approval of the Board of Trustees.
NYLIM may recoup the amount of any management fee waivers or expense
reimbursements from the Fund pursuant to the agreement if such action does not
cause the Fund to exceed existing expense limitations and the recoupment is made
within three years after the year in which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $12,178,588. It was unnecessary for NYLIM to reimburse the Fund for
expenses for the year ended October 31, 2007.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.35% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, Class R2 and Class R3 shares, has
adopted distribution plans (the "Plans") in accordance with the provisions of
Rule 12b-1 under the 1940 Act.

Pursuant to the Class A and Class R2 Plans, the Distributor receives a monthly
distribution fee from the Fund at an annual rate of 0.25% of the average daily
net assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly distribution fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
and Class C shares of the Fund. Pursuant to the Class R3 Plan, the Distributor
receives a monthly distribution fee from the Fund at the annual rate of 0.50% of
the average daily net assets of the Fund's Class R3 shares, which is an expense
of the Class R3 shares of the Fund for distribution or service activities as
designated by the Distributor. Class I and Class R1 shares are not subject to a
distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts

actually expended by the Distributor for distribution of the Fund's shares and
service activities.

In accordance with the Shareholder Services Plans for the Class R1, Class R2 and
Class R3 shares, the Manager has agreed to provide, through its affiliates or
independent third parties, various shareholder and administrative support
services to shareholders of the Class R1, Class R2 and Class R3 shares. For its
services, the Manager is entitled to a Shareholder Service Fee accrued daily and
paid monthly at an annual rate of 0.10% of the average daily net assets
attributable to the Class R1, Class R2 and Class R3 shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $322,025 for the year
ended October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $7,396, $424,652 and $29,993, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $3,134,032.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

NOTE 9--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years.

 28   MainStay MAP Fund


The changes to current generally accepted accounting principles from the
application of this Statement relate to the definition of fair value, the
methods used to measure fair value, and the expanded disclosures about fair
value measurements. As of October 31, 2007, the Fund does not believe the
adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay MAP Fund ("the Fund"), one of the
funds constituting The MainStay Funds, as of October 31, 2007, and the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years or periods in the four-year period
then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay MAP Fund of The MainStay Funds as of October 31, 2007, the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and financial highlights for
each of the years in the four-year period then ended, in conformity with U.S.
generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreements (each of the Management Agreement and the Subadvisory
Agreements, an "Agreement") between the Manager and Markston International LLC
("Markston") and between the Manager and Institutional Capital LLC ("ICAP"), a
wholly-owned indirect subsidiary of New York Life Investment Management Holdings
LLC ("NYLIM Holdings"), an affiliate of the Manager (each of Markston and ICAP,
a "Subadvisor"), at a meeting held on May 22 and 23, 2007.

In connection with the approval of each Agreement, the Trustees reviewed a
significant amount of a wide variety of information that they had requested and
received from the Manager and the Subadvisors, and data and analysis from an
outside data provider and a third party consultant. The Trustees considered
various industry trends and regulatory developments in their deliberations. In
considering approval of each Agreement, and in evaluating the fairness of the
compensation to be paid by the Fund, the Trustees met both as a full Board and
in executive session with no Interested Trustee present, in advance of the
meeting at which the Agreements were approved, and they considered a number of
factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and each Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisors have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisors' investment programs and investment results with
respect to the Fund, and each Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. Each Subadvisor is responsible for the day-to-day portfolio
management of a portion of the assets of the Fund, including determining the
composition of the portfolio of its portion of the Fund's assets and the timing
of the Fund's execution of the purchase and sale of assets, and its other
services include, among other services, providing reports to the Manager and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and each Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. The Board reviewed information
about each Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees noted that the Fund's assets
represented a significant portion of Markston's assets under management, and a
smaller portion of ICAP's assets under management. The Trustees considered the
Manager's supervision of the Fund's service providers and its attention to the
compliance program of the Trust, the Manager, each Subadvisor and certain other
service providers, as well as each Subadvisor's attention to its compliance
program. The Trustees noted the generally favorable results of a third party
review of the services and communications that NYLIM Service Company LLC, an
affiliate of the Manager and the Subadvisor, has provided to Trust shareholders.

The Board also considered the proposed subadvisory fee rate payable by the
Manager to each Subadvisor under its Subadvisory Agreement. The Board noted that
the subadvisory fee arrangement between the Manager and each Subadvisor included
breakpoints based on the amount of assets in the Subadvisor's portion of the
Fund's portfolio. The Board also considered and compared the rate of each
Subadvisor's proposed subadvisory fee to advisory fees paid by funds identified
by fund data services as comparable to the Fund. Based on these considerations,
the Board concluded that each Subadvisor's proposed subadvisory fee rate under
its Agreement was reasonable in comparison to other subadvisory fee rates.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board
took into consideration information it received on, among other things, the
favorable long- and short-term performance of the Fund under the monitoring of
the Manager, the favorable performance of Markston, and ICAP's favorable
performance in managing its portion of the Fund's assets. The Board further
considered the experience level, tenure and compensation of the management team
of each Subadvisor. The Board concluded that the investment program of each
Subadvisor appeared appropriately to complement the investment program of the
other Subadvisor.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates, and the subadvisory fee payments
made by the Manager to the Subadvisor. The Trustees were provided information
that indicated that the profitability to the Manager and its affiliates from the
Management Agreement with respect to the Fund and from the overall relationship
with the Trust was low. The Trustees considered other

                                                    www.mainstayfunds.com     31


benefits that the Manager and its affiliates receive from the relationship with
the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder
Services receive in exchange for services they provide to the Funds, and certain
benefits from soft dollar arrangements. The Trustees acknowledged certain
benefits to the reputation of the Manager and the Trust from their association
with each other. The Board considered that, in a transaction that closed on June
30, 2006, ICAP had entered into an agreement with NYLIM Holdings, at which time
ICAP became an affiliated person of the Manager.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at asset
levels above the breakpoint, and the fact that the breakpoint was intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund's management fee rate had been reduced by the breakpoint schedule
applicable to the Fund. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. Although the Trustees received fee and expense data with respect to
other clients of the Manager generally, they were advised that no other client
of the Manager had an investment strategy similar to that of the Fund. The
Trustees considered the current and proposed contractual and net management
fees, its anticipated gross and net expense ratio, and various components of the
expense ratio, in comparison to other funds in comparison groupings. The
Trustees generally acknowledged the historical relationships among the Manager,
the Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees noted the Manager's agreement to maintain the limit on the
Fund's net expenses at a certain level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax

Fund paid long-term capital gain distributions of $92,528,306.

The dividends paid by the Fund during the fiscal year ended October 31, 2007,

dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will

                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R3 shares are sold with
no initial sales charge or CDSC, have an annual 12b-1 fee of .50% and are
available in certain individual retirement accounts or in certain retirement
plans. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. These fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. The Manager may recoup the
amount of certain management fee waivers or expense reimbursements from the Fund
pursuant to the contract if such action does not cause the Fund to exceed
existing expense limitations and the recoupment is made within three years after
the year in which the Manager incurred the expense. From inception through
3/28/05 performance of Class I shares (first offered 3/29/05) includes the
historical performance of Class A shares adjusted to reflect the applicable
sales charge (or CDSC), fees, estimated expenses and fee waivers/expense
limitations of Class I shares upon initial offer. Prior to 4/28/06, performance
for Class R3 shares includes the historical performance of Class A shares

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MID CAP GROWTH FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Edmund C. Spelman of MacKay Shields LLC

HOW DID MAINSTAY MID CAP GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Mid Cap Growth Fund returned 25.53% for
Class A shares, 24.51% for Class B shares and 24.53% for Class C shares for the
12 months ended October 31, 2007. Over the same period, the Fund's Class I
shares returned 25.99% and Class R3 shares returned 25.13%. All share classes
underperformed the 26.07% return of the average Lipper(1) mid-cap growth fund
for the 12-month period. All share classes outperformed the 19.72% return of the
Russell Midcap(R) Growth Index,(2) the Fund's broad-based securities-market
index, for the 12 months ended October 31, 2007. See page 5 for Fund returns
with sales charges.

WHICH FACTORS HAD THE GREATEST IMPACT ON THE FUND'S PERFORMANCE DURING THE
REPORTING PERIOD?

The Fund's performance relative to the Russell Midcap(R) Growth Index resulted
primarily from stock selection in industrials, energy and consumer
discretionary. The weakest-performing sectors on an absolute basis were
financials, telecommunication services and consumer staples.

DURING THE REPORTING PERIOD, WHICH STOCKS WERE STRONG PERFORMERS AND WHICH WERE
WEAK?

The strongest contributors to the Fund's performance were energy equipment &
services firm National Oilwell Varco and independent petroleum refiner and
marketer Tesoro, both of which benefited from strong demand during a period of
rising oil prices. Construction company Fluor also performed well because of
ongoing demand for its engineering and contracting services.

Major detractors from the Fund's performance included wireless telecommunication
services company NII Holdings, electrical distributor WESCO International and
biopharmaceutical company MannKind. NII Holdings experienced weak subscription
growth. WESCO International saw a slowdown in demand among some of its key
end-markets. MannKind's lead product was delayed in clinical trials.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

The Fund initiated a new position in metals manufacturer, Precision Castparts,
and the stock performed well from the time it was purchased in late 2006 through
the end of October 2007. The company benefited from strong demand for its
products from the aerospace industry. The Fund also purchased shares of data
service center EQUINIX because its services remained in high demand as the
company expanded through the United States and internationally. The Fund sold
its positions in WESCO International and MannKind. The Fund also eliminated its
position in Capital One Financial on concerns about deterioration in the credit
markets.

HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, the Fund's allocation to financials decreased to an
underweight position in relation to the Russell Midcap(R) Growth Index. The
Fund's industrial holdings moved to a substantially overweight position. The
Fund's overweight position in energy relative to the Index declined primarily
because the sector's weighting in the Index increased.

At the end of October 2007, the Fund was overweight relative to the Russell
Midcap(R) Growth Index in energy and industrials, which helped performance. At
the same time, the Fund was underweight in consumer staples and financials,
which also benefited the Fund's results.


Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies. The
principal risk of growth stocks is that investors expect growth companies to
increase their earnings at a certain rate that is generally higher than the rate
expected for nongrowth companies. If these expectations are not met, the market
price for the stock may decline significantly, even if earnings showed an
absolute increase. The Fund may experience a portfolio turnover rate of more
than 100% and may generate taxable short-term capital gains.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Mid Cap
Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers five classes of shares. Class A shares, Class B shares
and Class C shares commenced on January 2, 2001. Class I shares commenced on
March 29, 2005. Class R3 shares commenced on April 28, 2006. Class A shares are
offered at net asset value per share plus an initial sales charge. No sales
charge applies on investments of $1 million or more (and certain other qualified
purchases) in Class A shares, but a contingent deferred sales charge is imposed
on certain redemptions of such shares within one year of the date of purchase.
Class B shares and Class C shares are offered without an initial sales charge,
although a declining contingent deferred sales charge may be imposed on
redemptions made within up to six years of purchase of Class B shares and a 1%
contingent deferred sales charge may be imposed on redemptions made within one
year of purchase of Class C shares. Class I and Class R3 shares are not subject
to a sales charge. As approved by the Board of Trustees in 1997, Class B shares
convert to Class A shares eight years after the date they were purchased. The
five classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A and Class R3 shares under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution
or service fee. Class R3 shares are authorized to pay to New York Life
Investment Management LLC, its affiliates, or third-party service providers, as
compensation for services rendered to shareholders of Class R3 shares, a
shareholder service fee.

The Fund's investment objective is to seek long-term growth of capital.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Investments
in mutual funds are valued at their net asset value as of the close of the New
York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Directors to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

 18   MainStay Mid Cap Growth Fund


(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 20) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.75% on assets up to $500 million and 0.70% on assets in
excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.50%; Class B, 2.25%; Class C, 2.25%; Class I, 1.12% and
Class R3, 1.72%. This expense limitation may be modified or terminated only with
the approval of the Board of Trustees. NYLIM may recoup the amount of any
management fee waivers or expense reimbursements from the Fund pursuant to the
agreement if such action does not cause the Fund to exceed existing expense
limitations and the recoupment is made within three years after the year in
which NYLIM incurred the expense.

                                                    www.mainstayfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $1,790,873 and recouped its fees in the amount of $141,868.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
 OCTOBER 31,
       2009*     TOTAL
            
   $18,665     $18,665
 ---------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.50% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C and Class R3 shares, has adopted
distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Pursuant to the Class R3 Plan, the Distributor receives a monthly distribution
fee from the Fund at the annual rate of 0.50% of the average daily net assets of
the Fund's Class R3 shares, which is an expense of the Class R3 shares of the
Fund for distribution or service activities as designated by the Distributor.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

In accordance with the Shareholder Services Plan for the Class R3 shares, the
Manager has agreed to provide, through its affiliates or independent third
parties, various shareholder and administrative support services to shareholders
of the Class R3 shares. For its services, the Manager is entitled to a
Shareholder Service Fee accrued daily and paid monthly at an annual rate of
0.10% of the average daily net assets attributable to the Class R3 shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $57,933 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $10,525, $89,785 and $12,304, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $690,033.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>

(G) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $8,873.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $50,545 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

acts as agent to the syndicate. Such commitment fees are allocated among the

NOTE 9--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Mid Cap Growth Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years or periods in the two-year period
then ended, and the financial highlights for each of the years or periods in the
four-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Mid Cap Growth Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years or periods in the two-year period then ended, and the
financial highlights for each of the years or periods in the four-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's favorable performance
over the medium and longer terms and its weaker recent performance.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate
to low and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered

                                                    www.mainstayfunds.com     25


potential benefits to the Manager and its affiliates arising from such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints that would reduce the Fund's management fee at asset
levels above the breakpoints, and the fact that the breakpoints were intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund not reached the asset level at which breakpoints would reduce the Fund's
management fee rate. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees took account of the Manager's willingness to maintain the management
fee waiver and expense limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.

expense limitations are contractual and may be modified or terminated only with
the approval of the Board of Trustees. The Manager may recoup the amount of
certain management fee waivers or expense reimbursements from the Fund pursuant
to the contract if such action does not cause the Fund to exceed existing
expense limitations and the recoupment is made within three years after the year
in which the Manager incurred the expense.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MID CAP VALUE FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

 8   MainStay Mid Cap Value Fund


PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Richard A. Rosen, CFA, and Mark T.
Spellman of MacKay Shields LLC

HOW DID MAINSTAY MID CAP VALUE FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK FOR THE 12-MONTH REPORTING PERIOD?

Excluding all sales charges, MainStay Mid Cap Value Fund returned 8.61% for
Class A shares, 7.82% for Class B shares and 7.75% for Class C shares for the 12
months ended October 31, 2007. Over the same period, the Fund's Class I shares
returned 9.24%, Class R1 shares returned 9.06% and Class R2 shares returned
8.84%. All share classes underperformed the 12.87% return of the average
Lipper(1) mid-cap value fund and the 9.73% return of the Russell Midcap(R) Value
Index(2) for the 12 months ended October 31, 2007. The Russell Midcap(R) Value
Index is the Fund's broad-based securities-market index. See page 5 for Fund
returns with sales charges.

WHICH SECTORS WERE STRONG CONTRIBUTORS DURING THE REPORTING PERIOD AND WHICH
SECTORS WERE WEAK?

Many sectors provided positive contributions to the Fund's performance during
the reporting period. Holdings in the health care and energy sectors were
particularly helpful, and more than offset weaker results from the consumer
discretionary and information technology sectors. Despite these positive
contributions, however, the Fund underperformed its peers and its benchmark.

DURING THE REPORTING PERIOD, WHAT WERE SOME OF THE FUND'S BEST-PERFORMING
INDIVIDUAL STOCKS?

KOS Pharmaceuticals, a maker of cholesterol-lowering drugs, was a strong
contributor to the Fund's performance during the reporting period. In November
2006, the company's shares, which we had purchased earlier in the year, were
acquired for a substantial premium by Abbott Labs. We eliminated the Fund's
entire position in mid-December by sale or tender. Supermarket chain Kroger was
also a strong performer. The company posted better-than-expected sales and
earnings for several consecutive quarters, and the market began to reward
investors with higher valuations. Kroger's restructuring efforts had clearly
begun to pay off, and the company confirmed its ability to compete with
heavyweights like Wal-Mart and Target. We trimmed the Fund's position in Kroger
as its shares approached our price target. Hess, an integrated oil company,
benefited when record high oil prices helped push its share price higher. The
company not only realized higher margins throughout the reporting period but
also increased its reserves with major oil and gas discoveries. We reduced the
Fund's position in Hess as the shares approached our price target late in the
reporting period.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

PMI Group was particularly weak. In light of difficulties in the mortgage
market, the company's exposure to subprime mortgages raised substantial investor
concerns. Since only 7% of the company's insurance is tied to subprime mortgages
and the stock was selling at a steep discount to book value, we believed that
PMI Group shares offered compelling value. We did reduce the Fund's position
during the reporting period, but the Fund continued to hold a small position in
the company.

Shares of E*Trade, initially purchased in February 2007, also traded lower
because of mortgage-related exposure. We sold the shares in August to reduce
mortgage-market vulnerability and to avoid the potential delays and risks
involved in the company's balance-sheet-restructuring plan. After the Fund's
sale, E*Trade's shares continued to decline sharply.

During the reporting period, shares of semiconductor manufacturer AMD declined
as price competition with rival Intel intensified, placing pressure on AMD's
prices and margins. After reviewing the investment, we concluded that the
company's earnings growth and free cash flow profile were no longer attractive.
In March, we sold the Fund's entire position in the stock.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

In addition to the transactions we've already mentioned, we initiated a number
of new positions in the Fund during the reporting period. These included global
pharmaceutical concern Teva Pharmaceutical Industries, discount retailer TJX,
managed care provider Coventry Health Care and mining machinery and equipment
manufacturer Joy Global.


The principal risk of investing in value stocks is that they may never reach
what the portfolio manager believes is their full value or they may even go down
in value. Mid-capitalization companies are generally less established and their
stocks may be more volatile and less liquid than the securities of large
companies. The Fund may experience a portfolio turnover rate of more than 100%
and may generate taxable short-term capital gains.

Among the positions we eliminated from the portfolio were industrial products
distributor W.W. Grainger, oil driller Pride International, newspaper and TV
station owner Tribune and auto parts manufacturer TRW Automotive.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2007, the Fund was overweight relative to the Russell
Midcap(R) Value Index in the health care, energy and industrials sectors. As of
the same date, the Fund was underweight in the financials, utilities, consumer
staples and consumer discretionary sectors.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Mid Cap
Value Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares. Class A shares and Class B
shares commenced on June 1, 1998. Class C shares commenced on September 1, 1998.
Class I shares, Class R1 shares and Class R2 shares commenced on January 2,
2004. Class A shares are offered at net asset value per share plus an initial
sales charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within up to six years of purchase of Class B
shares and a 1% contingent deferred sales charge may be imposed on redemptions
made within one year of purchase of Class C shares. Class I, Class R1 and Class
R2 shares are not subject to a sales charge. As approved by the Board of
Trustees in 1997, Class B shares convert to Class A shares eight years after the
date they were purchased. The six classes of shares bear the same voting (except
for issues that relate solely to one class), dividend, liquidation and other
rights and conditions except that Class B and Class C shares are subject to
higher distribution fee rates than Class A and Class R2 shares under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I and Class
R1 shares are not subject to a distribution or service fee. Class R1 and Class
R2 shares are authorized to pay to New York Life Investment Management LLC, its
affiliates, or third-party service providers, as compensation for services
rendered to shareholders of Class R1 or Class R2 shares, a shareholder service
fee.

The Fund's investment objective is to realize maximum long-term total return
from a combination of capital appreciation and income.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Options
contracts are valued at the last posted settlement price on the market where
such options are principally traded. Investments in mutual funds are valued at
their net asset value as of the close of the New York Stock Exchange on the date
of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects

 22   MainStay Mid Cap Value Fund


otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the effective interest rate method over the life of
the respective securities or, in the case of a callable security, over the
period to the first date of call. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 25) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are canceled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the price of the underlying security or foreign currency
increase. By writing a covered put option, the Fund, in exchange for the
premium, accepts the risk of a decline in the market value of the underlying
security or foreign currency below the exercise price. A call option may be
covered by the call writer's owning the underlying security throughout the
option period. A call option may also be covered by the call writer's
maintaining liquid assets valued at greater than the exercise price of the call
written. When writing a covered call option, the Fund, in return for the premium
on the option, gives up the opportunity to profit from a price increase in the
underlying securities above the exercise price, but, as long as the obligation
as the writer continues, has retained the risk of loss should the price of the
underlying security decline. After writing a put option, the Fund may incur a
loss equal to the difference between the exercise price of the option and the
sum of the market value of the underlying security plus the premium received
from the sale of the option.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option. (See Note 5 on page 26.)

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
rates last quoted by any major U.S. bank at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(I) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(J) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.70% on assets up to $500 million and 0.65% on assets in
excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.30%; Class B, 2.05%; Class C, 2.05%; Class I, 0.78%;
Class R1, 0.88% and Class R2, 1.13%. This expense limitation may be modified or
terminated only with the approval of the Board of Trustees. NYLIM may recoup the
amount of any management fee waivers or expense reimbursements from the Fund
pursuant to the agreement if such action does not cause the Fund to exceed
existing expense limitations and the recoupment is made within three years after
the year in which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $2,575,693 and waived its fees in the amount of $169,320.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
          OCTOBER 31,
  2008*       2009       2010      TOTAL
                         
 $130,177   $347,680   $169,320   $647,177
 -----------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.30% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

 24   MainStay Mid Cap Value Fund


State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, and Class R2 shares, has adopted
distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act.

Pursuant to the Class A and Class R2 Plans, the Distributor receives a monthly
distribution fee from the Fund at an annual rate of 0.25% of the average daily
net assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly distribution fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
and Class C shares of the Fund. Class I and Class R1 shares are not subject to a
distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

In accordance with the Shareholder Services Plans for the Class R1 and Class R2
shares, the Manager has agreed to provide, through its affiliates or independent
third parties, various shareholder and administrative support services to
shareholders of the Class R1 and Class R2 shares. For its services, the Manager
is entitled to a Shareholder Service Fee accrued daily and paid monthly at an
annual rate of 0.10% of the average daily net assets attributable to the Class
R1 and Class R2 shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $50,794 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $3,179, $177,971 and $2,582, respectively, for the year ended October
31, 2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $1,062,010.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20

NOTE 10--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the

                                                    www.mainstayfunds.com     27

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Fund's 2008 fiscal year, and is to be applied to all open tax years as of the
date of effectiveness. Based on Management's analysis, the determination has
been made that the adoption of the interpretation on November 1, 2007 did not
have an impact on the Fund's financial statements upon adoption. Management
continually reviews the Fund's tax positions and such conclusions under the
Interpretation based on factors, including, but not limited to, ongoing analyses
of tax laws, regulations and interpretations, thereof.

In September 2006, the FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Mid Cap Value Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by appropriate auditing procedures where replies from brokers
were not received. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Mid Cap Value Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years or periods in the four-year period then ended,
in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's underperformance
relative to certain measures over several timeperiods and its modest improvement
since a portfolio manager change in the past two years.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate,
and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

 30   MainStay Mid Cap Value Fund


The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints that would reduce the Fund's management fee at asset
levels above the breakpoints, and the fact that the breakpoints were intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund not reached the asset level at which breakpoints would reduce the Fund's
management fee rate. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees took account of the Manager's willingness to maintain the management
fee waiver and expense limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $51,454,138.

The dividends paid by the Fund during the fiscal year ended October 31, 2007,
should be multiplied by 100.0% to arrive at the amount eligible for qualified
dividend income, 33.2% for qualified interest income and 100.0% for the
corporate dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will
be the amounts you are to use on your federal income tax return and will differ
from the amounts which we must report for the Fund's fiscal year ended October
31, 2007.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables do not reflect the deduction of taxes that a shareholder
would pay on distributions or Fund-share redemptions. Total returns reflect
change in share price and reinvestment of dividend and capital-gain
distributions. Class A, B and C shares are sold with no initial sales charge or
contingent deferred sales charge (CDSC) and have no annual 12b-1 fees.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. These fee waivers and/or
expense limitations are contractual and may be modified or terminated only with
the approval of the Board of Trustees. The Manager may recoup the amount of
certain management fee waivers or expense reimbursements from the Fund pursuant
to the contract if such action does not cause the Fund to exceed existing
expense limitations and the recoupment is made within three years after the year
in which the Manager incurred the expense. Prior to 9/1/98, the performance of
Class C shares includes the historical performance of Class B shares.

1. As of 10/31/07, MainStay Money Market Fund had an effective 7-day yield of
   4.58% for Class A, B and C shares. The 7-day current yield was 4.52%, 4.52%
   and 4.53% for Class A, B and C shares, respectively. These yields reflect
   certain expense limitations. Had these expense limitations not been in
   effect, the effective 7-day would have been 4.43 for Class A, B and C shares
   and the 7-day current yield would have been 4.35% for Class A, 4.45% for
   Class B and 4.30% for Class C. The fee waivers and/or expense limitations are
   contractual and may be modified or terminated only with the approval of the
   Board of Directors. The current yield is more reflective of the Fund's
   earnings than the total return.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MONEY MARKET FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

 8   MainStay Money Market Fund


PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Claude Athaide, Ph.D., CFA, of MacKay
Shields LLC

HOW DID MAINSTAY MONEY MARKET FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

As of October 31, 2007, MainStay Money Market Fund Class A and Class B shares
had a 7-day cur-rent yield of 4.52% and Class C shares had a 7-day current yield
of 4.53%. All share classes had a 7-day effective yield of 4.58% as of the same
date. For the 12 months ended October 31, 2007, MainStay Money Market Fund
returned 4.69% for Class A, Class B and Class C shares. All share classes
outperformed the 4.55% return of the average Lipper(1) money market fund for the
12 months ended October 31, 2007.

WHAT FACTORS CONTRIBUTED TO THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

Real gross domestic product (GDP) grew 2.85% during the 12 months ended
September 30, 2007. Personal spending increased 2.9%, supported by a 3.8%
increase in real disposable income as nonfarm payrolls increased by 1.57 million
during the period. The trade deficit narrowed, as export growth exceeded import
growth by 8.5%. Residential investment declined by 16.3% during the period.

Major stories during the reporting period included the recession in the housing
market and a major movement toward higher-quality fixed-income securities.
Rising delinquencies among newly underwritten subprime mortgage loans caught
many investors by surprise in late 2006. The delinquencies caused the value of
mortgage securities backed by these loans to fall dramatically. The yield on the
two-year Treasury note fell to 4.51% in early March.

As economic growth picked up in the spring, Treasury yields rose again, with the
yield on the two-year Treasury note reaching 5.1% in June. The rising yield
trend reversed in the middle of June, as news of losses suffered by hedge funds
investing in collateralized debt obligations sparked another round in the
"flight to quality," or the general migration toward lower-risk bonds. Since
June 2007, several other institutions have reported losses on leveraged loans,
subprime mortgages and other structured products.

In August, the Federal Open Market Committee (FOMC) cut the primary discount
rate in an effort to alleviate the increasingly illiquid conditions in the money
markets. In the following weeks, the FOMC continued to take action to encourage
banks to use the discount window to fund assets. These steps were designed to
help banks ease the dislocations in the money markets.

During the last six weeks of the reporting period, the FOMC cut the targeted
federal funds rate by a total of 75 basis points and cut the primary discount
rate a second time. (A basis point is one-hundredth of a percentage point.) The
FOMC stated that its actions were intended to help prevent some of the adverse
effects on the broader economy that might otherwise arise from the disruptions
in the financial markets. Liquidity did improve somewhat during the reporting
period after the FOMC began lowering rates.

After averaging 38 basis points during the first half of 2007, the difference
between three-month Treasury-bill yields and three-month LIBOR(2) rose to 240
basis points in August. The T-bill-to-LIBOR spread is used as a measure of
credit risk. All told, the yield on the three-month Treasury bill fell from
5.08% at the end of October 2006 to 3.94% at the end of October 2007, or a total
of 114 basis points. Three-month LIBOR declined 48 basis points, from 5.37% to
4.89% over the same 12-month period.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

The Fund invested in securities issued by U.S. government sponsored entities and
in first-tier securities issued by finance, insurance, brokerage and industrial
companies, as well as banks and bank holdings companies. The Fund did not own
any commercial paper issued by structured investment vehicles (SIVs).

WHAT WAS THE FUND'S DOLLAR-WEIGHTED AVERAGE MATURITY AT THE END OF THE REPORTING
PERIOD?

As of October 31, 2007, the dollar-weighted average maturity of the Fund was
approximately 63 days.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Money
Market Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. As approved by the Board of Trustees in 1997,
Class B shares convert to Class A shares eight years after the date they were
purchased. The three classes of shares bear the same voting (except for issues
that relate solely to one class), dividend, liquidation and other rights and
conditions.

The Fund's investment objective is to seek as high a level of current income as
is considered consistent with the preservation of capital and liquidity.

The Fund's principal investments include derivatives such as variable rate
master demand notes, "floating-rate notes" and mortgage-related and asset-backed
securities. If expectations about change in interest rates, or assessments of an
issuer's credit worthiness or market conditions are wrong, the use of
derivatives or other investments could result in a loss.

The Fund invests in foreign securities, which carry certain risks in addition to
the usual risks inherent in domestic instruments. These risks include those
resulting from future adverse political and economic developments and possible
imposition of currency exchange blockages or other foreign governmental laws and
restrictions. The ability of issuers of debt securities held by the Fund to meet
their obligations may be affected by economic developments in a specific
industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) VALUATION OF FUND SHARES.  The Fund seeks to maintain a net asset value of
$1.00 per share, although there is no assurance that it will be able to do so on
a continuous basis, and it has adopted certain investment, portfolio and
dividend and distribution policies designed to enable it to do so. An investment
in the Fund is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.

(B) SECURITIES VALUATION.  Securities are valued at their amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between such cost and the value on maturity date.

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund declares dividends of net investment
income daily and are paid monthly and distributions of net realized capital
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are reclassified amongst undistributed net
investment income, accumulated net realized gain or loss and paid-in-capital.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued daily and discounts and premiums on securities purchased for the Fund
are accreted and amortized, respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments
are allocated to separate classes of shares based upon their relative net assets
on the date the income is earned or realized and unrealized gains and losses are
incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 19) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(G) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported

 18   MainStay Money Market Fund


amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.
NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.50% on assets up to $300 million, 0.45% on assets from
$300 million to $700 million, 0.40% on assets from $700 million to $1.0 billion
and 0.35% on assets in excess of $1.0 billion.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 0.70%; Class B, 0.70% and Class C, 0.70%. This expense
limitation may be modified or terminated only with the approval of the Board of
Trustees. NYLIM may recoup the amount of any management fee waivers or expense
reimbursements from the Fund pursuant to the agreement if such action does not
cause the Fund to exceed existing expense limitations and the recoupment is made
within three years after the year in which NYLIM incurred the expense. For the
year ended October 31, 2007, NYLIM earned fees from the Fund in the amount of
$2,458,683 and waived its fees in the amount of $649,067.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
          OCTOBER 31,
 2008*        2009        2010       TOTAL
                          
$232,330   $1,058,259   $649,067   $1,939,656
- ---------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
0.70% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) CONTINGENT DEFERRED SALES CHARGE.  Although the Fund does not assess a
contingent deferred sales charge upon redemption of Class B or Class C shares of
the Fund, the applicable contingent deferred sales charge will be assessed when
shares were redeemed from the Fund if the shareholder previously exchanged his
or her investment into the Fund from another Fund in the Trust. The Fund was
advised that NYLIFE Distributors LLC (the "Distributor"), an indirect wholly
owned subsidiary of New York Life, received from shareholders the proceeds from
contingent deferred sales charges for the year ended October 31, 2007, in the
amount of $295,055.

(C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing

                                                    www.mainstayfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

agent. NYLIM Service has entered into an agreement with Boston Financial Data
Services pursuant to which it performs certain services for which NYLIM Service
is responsible. Transfer agent expenses incurred by the Fund, for the year ended
October 31, 2007, amounted to $1,323,231.

(D) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(E) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>
                                                      
Class A                                         $592         0.0*%
- --------------------------------------------------------------------
Class C                                          114          0.0*
- --------------------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(F) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $18,933.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $77,945 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:
As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

The other temporary differences are primarily due to distribution payable.

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $252 were available as shown in the table below, to the extent provided by
the regulations to offset future realized gains of the Fund through the years
indicated. To the extent that these loss carryforwards are used to offset future
capital gains, it is probable that the capital gains so offset will not be
distributed to shareholders.

NOTE 7--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts.

NOTE 8--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Money Market Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Money Market Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years or periods in the four-year period then ended,
in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor, including that the Fund is a money
market fund. The Trustees reviewed the services that the Manager and the
Subadvisor have provided historically to the Fund, and also generally to other
series of the Trust. Among other services, the Manager's services have included
investment management services, including monitoring and evaluating the
Subadvisor's investment program and investment results with respect to the Fund,
and the Subadvisor's compliance with the Fund's investment policies and
restrictions, and administrative services, including working with other service
providers of the Trust, maintaining certain Fund records, providing office
space, performing clerical and bookkeeping services for the Fund, preparing
Board materials and Fund filings, and otherwise managing the Trust's operations.
The Subadvisor is responsible for the day-to-day portfolio management of the
Fund, including determining the composition of assets of the Fund and the timing
of the Fund's execution of the purchase and sale of assets, and its other
services include, among other services, providing reports to the Manager and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. The Board reviewed reports on
the Subadvisor's brokerage practices, including with respect to best execution
of portfolio trades. The Trustees considered the Manager's supervision of the
Fund's service providers and its attention to the compliance program of the
Trust, the Manager, the Subadvisor and certain other service providers, as well
as the Subadvisor's attention to its compliance program. The Trustees noted the
generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's investment performance
that was slightly below peer median over various periods of time and the
sensitivity to expenses of the comparative performance of the Fund.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement, and from the overall relationship with
the Trust, was low. The Trustees considered other benefits that the Manager and
its affiliates receive from the relationship with the Trust, including benefits
that NYLIFE Distributors and MainStay Shareholder Services receive in exchange
for services they provide to the Funds, and certain benefits from soft dollar
arrangements. The Trustees acknowledged certain benefits to the reputation of
the Manager and the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual

                                                    www.mainstayfunds.com     23


breakpoints that would reduce the Fund's management fee at asset levels above
the breakpoints, and the fact that the breakpoints were intended to provide that
shareholders would share in benefits from economies of scale obtained through
the growth in the Fund's assets. The Trustees noted that the Fund's management
fee rate had been reduced by the breakpoint schedule applicable to the Fund. The
Trustees reviewed information about the potential effect of asset growth on Fund
expenses, the difficulty of forecasting its effect on the profitability of the
Manager and its affiliates, and the management fee breakpoints applicable to the
Fund and certain other funds. It was noted that, to the extent the Fund's gross
expenses currently were higher than its net expenses, the reduction of the
Fund's gross expenses through the achievement of economies of scale might
benefit the Manager by reducing the expenses the Manager must reimburse to the
Fund rather than directly benefiting the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other registered money market fund clients of the Manager and Subadvisor, and
took account of explanations and other information relating to the fees and
expenses of those other funds and accounts. The Trustees considered the current
and proposed contractual and net management fees, its anticipated gross and net
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationships among the Manager, the Subadvisor and the Trust and the
likely difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager. The Trustees took account of the
Manager's willingness to maintain the management fee waiver and expense
limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SMALL CAP GROWTH FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Edmund C. Spelman of MacKay Shields LLC

HOW DID MAINSTAY SMALL CAP GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK FOR THE 12-MONTH REPORTING PERIOD?

Excluding all sales charges, MainStay Small Cap Growth Fund returned 5.53% for
Class A shares, 4.73% for Class B shares and 4.80% for Class C shares for the 12
months ended October 31, 2007. Over the same period, Class I shares returned
6.18%. All share classes underperformed the 20.33% return of the average
Lipper(1 )small-cap growth fund and the 16.73% return of the Russell 2000(R)
Growth Index(2) for the 12 months ended October 31, 2007. The Russell 2000(R)
Growth Index is the Fund's broad-based securities-market index. See page 5 for
Fund returns with sales charges.

WHICH SECTORS HAD THE GREATEST POSITIVE OR NEGATIVE IMPACT ON THE FUND'S
RELATIVE PERFORMANCE DURING THE REPORTING PERIOD?

Favorable stock selection in the energy and consumer staples sectors helped the
Fund's performance during the 12 months ended October 31, 2007. An overweight
position in the energy sector also helped the Fund's relative results, as did an
underweight position in consumer discretionary and financial stocks. This,
however, was not enough to overcome poor stock selection in the information
technology, consumer discretionary and industrials sectors. In addition, an
underweight position in materials and an overweight position in the consumer
staples sector detracted from the Fund's relative performance.

WHAT WERE SOME OF THE FUND'S STOCK-SPECIFIC SUCCESS STORIES DURING THE REPORTING
PERIOD?

Dawson Geophysical and OYO Geospace were among the Fund's top performers. Both
companies benefited from strong demand for seismic data services for oil and gas
exploration. Specialty mattress manufacturer Tempur-Pedic International saw
strong earnings growth as it rolled out several new product lines and expanded
its distribution channels. Central European Distribution, a distributor of
alcoholic beverages, saw strong growth in Poland and other European countries
and continued to expand its capacity. Layne Christensen, whose products and
services are used in mineral and energy exploration as well as development of
water resources, benefited from strong demand.

WHICH INDIVIDUAL STOCKS LOST GROUND DURING THE REPORTING PERIOD?

Among the Fund's worst performers were specialty apparel retailers The
Children's Place and Charlotte Russe. Both companies suffered from weak retail
sales and fashion misses. Integrated circuit manufacturer Trident Microsystems
faced competition from lower-priced competitors. Overcapacity and weak demand
hurt regional trucking company Celadon Group, while Palomar Medical Technologies
experienced slower-than-expected demand for its cosmetic laser products.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

Dawson Geophysical, TempurPedic International, Central European Distribution,
OYO Geospace and Layne Christensen were all new purchases during the reporting
period, and all were strong performers. The Fund also established new positions
in contract research organization PAREXEL International and apparel manufacturer
Warnaco Group. Each of these purchases contributed positively to the Fund's
performance during the reporting period.

WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD?

We eliminated the Fund's holdings in construction equipment supplier ASV,
biotechnology firm Nektar Therapeutics, specialty retailer Hibbett Sports and
homebuilder Beazer Homes. All of these companies have since experienced
disappointing earnings or unfavorable corporate developments, and the sales
helped the Fund's relative results.

HOW DID THE FUND CHANGE ITS SECTOR WEIGHTINGS DURING THE REPORTING PERIOD?

During the 12 months ended October 31, 2007, we increased the Fund's weightings
in the energy, materials and consumer staples sectors. We decreased the Fund's
weightings in the consumer


The principal risk of growth stocks is that investors expect growth companies to
increase their earnings at a certain rate that is generally higher than the rate
expected for nongrowth companies. If these expectations are not met, the market
price of the stock may decline significantly, even if earnings showed an
absolute increase. Stocks of small companies may be subject to higher price
volatility, significantly lower trading volumes and greater spreads between bid
and ask prices than stocks of larger companies. Small companies may be more
vulnerable to adverse business or market developments than mid- or
large-capitalization companies. The Fund may experience a portfolio turnover
rate of more than 100% and may generate taxable short-term capital gains.

discretionary, health care, industrials and financials sectors.

As of October 31, 2007, the Fund was overweight relative to the Russell 2000(R)
Growth Index in the energy, consumer staples and industrials sectors. On the
same date, the Fund was underweight in the health care and consumer
discretionary sectors. The Fund was roughly market weight in the information
technology, materials and financial sectors and had no representation in the
telecommunication services and utilities sectors. On a cumulative basis,
relative sector positioning detracted modestly from the Fund's performance

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Small Cap
Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares and Class B
shares commenced on June 1, 1998. Class C shares commenced on September 1, 1998.
Class I shares commenced on May 31, 2006. Class A shares are offered at net
asset value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within up to six years of purchase of Class B shares and a 1% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are not subject to a sales charge. As
approved by the Board of Trustees in 1997, Class B shares convert to Class A
shares eight years after the date they were purchased. The four classes of
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that Class B and
Class C shares are subject to higher distribution fee rates than Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek long term-capital appreciation by
investing primarily in securities of small-capitalization companies.

Small-capitalization companies may be more volatile in price and have
significantly lower trading volumes than companies with larger capitalizations.
They may be more vulnerable to adverse business or market developments than
larger-capitalization companies.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Investments
in mutual funds are valued at their net asset value as of the close of the New
York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007 the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent book/tax differences
relating to income and gains are

 20   MainStay Small Cap Growth Fund


reclassified amongst undistributed net investment income, accumulated net
realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 22) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 1.00% on assets up to $1.0 billion and 0.95% on assets in
excess of $1.0 billion. NYLIM has contractually agreed to waive its management
fee by 0.15% to 0.85% on assets up to $1.0 billion and to 0.80% on assets in
excess of $1.0 billion, which is not recoupable.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.48%; Class B, 2.23%; Class C, 2.23% and Class I, 0.93%.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. NYLIM may recoup the amount of any management fee waivers
or expense reimbursements from the Fund pursuant to the

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

agreement if such action does not cause the Fund to exceed existing expense
limitations and the recoupment is made within three years after the year in
which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $2,049,086 and waived its fees in the amount of $793,792 of which
$486,411 is recoupable.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
          OCTOBER 31,
 2008*       2009         2010       TOTAL
                          
$174,275   $705,943     $486,411   $1,366,629
- ---------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, the Manager had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.48% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 9 on page
24.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $32,348. Additional payments were
made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $29,536 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $2,528, $145,642 and $1,372, respectively, for the year ended October
31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $936,280.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

 22   MainStay Small Cap Growth Fund


(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net

Class I                               3,136,474         83.8
- ------------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(H) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $7,673.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $47,157 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

 ----------------------------------------------------------------------
</Table>

The difference between book-basis and tax basis unrealized appreciation is
primarily due to wash sales deferrals.

The following table discloses the current year reclassifications between
accumulated net investment loss and additional paid-in capital, arising from
permanent differences; net assets at October 31, 2007 are not affected.

 -------------------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to net operating losses.

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $77,199,117 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

</Table>

The Fund utilized $56,207,711 of capital loss carryforwards during the year
ended October 31, 2007.

NOTE 5--CUSTODIAN:

SSBT is the custodian of cash and securities of the Fund. Custodial fees are
charged to the Fund based on the market value of securities in the Fund and the
number of certain cash transactions incurred by the Fund.

NOTE 6--LINE OF CREDIT:

The Fund, and certain affiliated funds, maintain a line of credit of
$160,000,000 with a syndicate of banks in order to secure a source of funds for
temporary purposes to meet unanticipated or excessive shareholder redemption
requests. These funds pay a commitment fee, at an annual rate of .060% of the
average commitment amount, regardless of usage, to The Bank of New York, which
acts as agent to the syndicate. Such commitment fees are allocated among the
funds based upon net assets and other factors. Interest on any revolving credit

NOTE 9--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the MainStay
Small Cap Growth Fund was $38,000. NYLIM has reimbursed or paid all expenses
relating to the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in

 24   MainStay Small Cap Growth Fund


filing tax returns (including whether an entity is taxable in a particular
jurisdiction), and requires certain expanded tax disclosures. The Interpretation
becomes effective for the Fund's 2008 fiscal year, and is to be applied to all
open tax years as of the date of effectiveness. Based on Management's analysis,
the determination has been made that the adoption of the interpretation on
November 1, 2007, did not have an impact on the Fund's financial statements upon
adoption. Management continually reviews the Fund's tax positions and such
conclusions under the Interpretation based on factors, including, but not
limited to, ongoing analyses of tax laws, regulations and interpretations,
thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Small Cap Growth Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years or periods in the
two-year period then ended, and the financial highlights for each of the years
or periods in the four-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate procedures where replies from brokers were
not received. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Small Cap Growth Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years or periods in the two-year period then ended, and the
financial highlights for each of the years or periods in the four-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor, including with respect to the Fund's
emphasis on investing in small cap growth stocks. The Trustees reviewed the
services that the Manager and the Subadvisor have provided historically to the
Fund, and also generally to other series of the Trust. Among other services, the
Manager's services have included investment management services, including
monitoring and evaluating the Subadvisor's investment program and investment
results with respect to the Fund, and the Subadvisor's compliance with the
Fund's investment policies and restrictions, and administrative services,
including working with other service providers of the Trust, maintaining certain
Fund records, providing office space, performing clerical and bookkeeping
services for the Fund, preparing Board materials and Fund filings, and otherwise
managing the Trust's operations. The Subadvisor is responsible for the
day-to-day portfolio management of the Fund, including determining the
composition of assets of the Fund and the timing of the Fund's execution of the
purchase and sale of assets, and its other services include, among other
services, providing reports to the Manager and reviewing certain aspects of Fund
filings. The Trustees considered, among other things, the Manager's and
Subadvisor's management, personnel, resources, operations and portfolio
management capabilities. The Board reviewed reports on the Subadvisor's
brokerage practices, including with respect to best execution of portfolio
trades. The Trustees considered the Manager's supervision of the Fund's service
providers and its attention to the compliance program of the Trust, the Manager,
the Subadvisor and certain other service providers, as well as the Subadvisor's
attention to its compliance program. The Trustees noted the generally favorable
results of a third party review of the services and communications that NYLIM
Service Company LLC, an affiliate of the Manager and the Subadvisor, has
provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's underperformance when
compared over several time periods with groupings of funds having similar
investment mandates.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate,
and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered

                                                    www.mainstayfunds.com     27


potential benefits to the Manager and its affiliates arising from such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at asset
levels above the breakpoint, and the fact that the breakpoint was intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund not reached the asset level at which the breakpoint would reduce the Fund's
management fee rate. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees noted the Manager's agreement to continue to waive a certain portion of
its management fee and maintain the existing contractual limitation on the
Fund's net expenses.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available
to corporate and institutional investors with a minimum initial investment of $5
million. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. These fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. The Manager may recoup the
amount of certain management fee waivers or expense reimbursements from the Fund
pursuant to the contract if such action does not cause the Fund to exceed
existing expense limitations and the recoupment is made within three years after
the year in which the Manager incurred the expense. From inception (6/1/98)

 6 MainStay Small Cap Value Fund


COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SMALL CAP VALUE FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES

The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Mark T. Spellman of MacKay Shields LLC

HOW DID MAINSTAY SMALL CAP VALUE FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK FOR THE 12-MONTH REPORTING PERIOD?

Excluding all sales charges, MainStay Small Cap Value Fund returned -4.62% for
Class A shares, -5.34% for Class B shares and -5.41% for Class C shares for the
12 months ended October 31, 2007. Over the same period, Class I shares returned
- -4.63%. All share classes underperformed the 6.26% return of the average
Lipper(1) small-cap value fund and the 2.05% return of the Russell 2000(R) Value
Index(2) for the 12 months ended October 31, 2007. The Russell 2000(R) Value
Index is the Fund's broad-based securities-market index. See page 5 for Fund
returns with sales charges.

DURING THE REPORTING PERIOD, WHAT WERE SOME OF THE FUND'S BEST-PERFORMING
INDIVIDUAL STOCKS?

The Fund purchased shares of Cooper Tire & Rubber in December 2006. The company
benefited from better product pricing and volume and from wage and benefit
concessions from a unionized workforce. We eliminated the position at the end of
June when the stock reached our price target. After the sale, the stock declined
sharply. Glass maker Apogee Enterprises was also a strong performer.
Improvements in operations led to higher cash flows, and the company's stock
price responded favorably. We eliminated the holding in June, when the shares
hit our price target. Ship transportation company Genco Shipping & Trading rose
sharply after we first purchased the stock in June 2007. The advance was driven
by excellent volume and pricing trends in the company's mineral and agricultural
cargo shipping businesses. Although we trimmed the position, the stock remained
part of the Fund's portfolio.

WHICH STOCKS DETRACTED FROM THE PERFORMANCE DURING THE REPORTING PERIOD?

Paperboard manufacturer Caraustar Industries faced difficult industry
fundamentals that weighed on its shares. We sold the Fund's position in the
stock in early January on the belief that improvements would take several
quarters. After the sale, the stock con-tinued to decline sharply. The Fund's
position in American Home Mortgage Investment was hurt by a liquidity crunch,
when lines of credit were pulled at sponsor banks during the subprime mortgage
crisis. Without lines of credit, mortgage providers cannot conduct normal
business. We eliminated the Fund's position in American Home Mortgage Investment
in early August, shortly before the company filed for Chapter 11 bankruptcy
protection. The Fund's position in homebuilder TOUSA was negatively affected by
the downturn in the housing market. The company's shares fell sharply during the
reporting period, and the Fund's position has since been sold.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

The Fund's most significant purchases included Cooper Tire & Rubber and Genco
Shipping & Trading. Other purchases included Stone Energy and Alpha Natural
Resources. Significant sales included Cooper Tire & Rubber, Caraustar Industries
and American Home Mortgage Investment. Other sales included Premium Global
Services and SafeNet.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2007, the Fund was overweight in energy relative to the
Russell 2000(R) Value Index. This positioning contributed positively to the
Fund's performance. The Fund was also overweight in consumer discretionary and
industrials, which detracted from performance. On the same date, the Fund was
underweight in health care, financials, information technology and consumer
staples, which detracted from relative performance.


Stocks of small companies may be subject to higher price volatility,
significantly lower trading volumes and greater spreads between bid and ask
prices than stocks of larger companies. Small companies may be more vulnerable
to adverse business or market developments than mid- or large-capitalization
companies. The principal risk of investing in value stocks is that they may
never reach what the portfolio manager believes is their full value or they may
even go down in value.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Small Cap
Value Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares and Class B
shares commenced on June 1, 1998. Class C shares commenced on September 1, 1998.
Class I shares commenced on February 16, 2005. Class A shares are offered at net
asset value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within up to six years of purchase of Class B shares and a 1% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are not subject to a sales charge. As
approved by the Board of Trustees in 1997, Class B shares convert to Class A
shares eight years after the date they were purchased. The four classes of
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that Class B and
Class C shares are subject to higher distribution fee rates than Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution or service fee.

The Fund's investment objective is to seek long-term capital appreciation by
investing primarily in securities of small-capitalization companies.

Small-capitalization companies may be more volatile in price and have
significantly lower trading volumes than companies with larger capitalizations.
They may be more vulnerable to adverse business or market developments than
large-capitalization companies.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Investments
in mutual funds are valued at their net asset value as of the close of the New
York Stock Exchange on the date of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the Fund, at net asset value, unless the shareholder elects otherwise.
Dividends and distributions to shareholders are determined in accordance with
federal income tax regulations and may differ from generally accepted accounting
principles in the United States of America. Permanent

 18   MainStay Small Cap Value Fund


book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (B) on
page 20) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.85% on assets up to $1.0 billion and 0.80% on assets in
excess of $1.0 billion. NYLIM has also contractually agreed to waive a portion
of its management fee so that the management fee is 0.60% on assets up to $1.0
billion and 0.55% on assets in excess of $1.0 billion.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.55%; Class B, 2.30%; Class C, 2.30%; and Class I, 1.24%.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. NYLIM may recoup the amount of any management fee waivers
or expense reimbursements from the Fund pursuant to the

                                                     www.mainstayfunds.com    19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

agreement if such action does not cause the Fund to exceed existing expense
limitations and the recoupment is made within three years after the year in
which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $859,258 and waived its fees in the amount of $252,723.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.55% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

As of October 31, 2007, there is no amount of waived fees that are subject to
possible recoupment by the Manager.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $19,269 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $370, $47,716 and $2,294, respectively, for the year ended October 31,
2007.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $360,116.

(E) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(F) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

* Less than one-tenth of a percent.

(G) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $3,690.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $35,582 for the year ended
October 31, 2007.

NOTE 9--OTHER MATTERS:

In 2004 the Securities and Exchange Commission ("SEC") raised concerns relating
to a guarantee provided to shareholders of the MainStay Equity Index Fund and
the fees and expenses of that Fund, as well as the related guaranteed disclosure
to that fund's shareholders. Discussions have been held with the SEC concerning
a possible resolution of this matter. There can be no assurance at this time as
to the outcome of these efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Small Cap Value Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or other appropriate auditing procedures where replies from brokers
were not received. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Small Cap Value Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years or periods in the four-year period then ended,
in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS.

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor, including with respect to the Fund's
emphasis on investing in small cap value stocks. The Trustees reviewed the
services that the Manager and the Subadvisor have provided historically to the
Fund, and also generally to other series of the Trust. Among other services, the
Manager's services have included investment management services, including
monitoring and evaluating the Subadvisor's investment program and investment
results with respect to the Fund, and the Subadvisor's compliance with the
Fund's investment policies and restrictions, and administrative services,
including working with other service providers of the Trust, maintaining certain
Fund records, providing office space, performing clerical and bookkeeping
services for the Fund, preparing Board materials and Fund filings, and otherwise
managing the Trust's operations. The Subadvisor is responsible for the
day-to-day portfolio management of the Fund, including determining the
composition of assets of the Fund and the timing of the Fund's execution of the
purchase and sale of assets, and its other services include, among other
services, providing reports to the Manager and reviewing certain aspects of Fund
filings. The Trustees considered, among other things, the Manager's and
Subadvisor's management, personnel, resources, operations and portfolio
management capabilities. The Board reviewed reports on the Subadvisor's
brokerage practices, including with respect to best execution of portfolio
trades. The Trustees considered the Manager's supervision of the Fund's service
providers and its attention to the compliance program of the Trust, the Manager,
the Subadvisor and certain other service providers, as well as the Subadvisor's
attention to its compliance program. The Trustees noted the generally favorable
results of a third party review of the services and communications that NYLIM
Service Company LLC, an affiliate of the Manager and the Subadvisor, has
provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's underperformance over
several time periods relative to groupings of funds having similar mandates.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the overall relationship with the Trust was low, and, with
respect to the Fund in particular, the Manager and its affiliates were not
making a profit. The Trustees considered other benefits that the Manager and its
affiliates receive from the relationship with the Trust, including benefits that
NYLIFE Distributors and MainStay Shareholder Services receive in exchange for
services they provide to the Funds, and certain benefits from soft dollar
arrangements. The Trustees acknowledged certain benefits to the reputation of
the Manager and the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

 24   MainStay Small Cap Value Fund


The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at asset
levels above the breakpoint, and the fact that the breakpoint was intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund not reached the asset level at which the breakpoint would reduce the Fund's
management fee rate. They also noted the Manager's willingness to waive and/or
reimburse contractually a portion of the Fund's expenses. The Trustees reviewed
information about the potential effect of asset growth on Fund expenses, the
difficulty of forecasting its effect on the profitability of the Manager and its
affiliates, and the management fee breakpoints applicable to the Fund and
certain other funds. It was noted that, to the extent the Fund's gross expenses
currently were higher than its net expenses, the reduction of the Fund's gross
expenses through the achievement of economies of scale might benefit the Manager
by reducing the expenses the Manager must reimburse to the Fund rather than
directly benefiting the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered that comparative data with respect to other
clients of the Manager or Subadvisor was not available as such clients did not
have similar investment mandates as the Fund. The Trustees considered the
current and proposed contractual and net management fees, its anticipated gross
and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees noted the Manager's agreement to continue to waive a certain portion of
its management fee and maintain the existing contractual limitation on the
Fund's net expenses.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $11,959,751.

The dividends paid by the Fund during the fiscal year ended October 31, 2007,
should be multiplied by 20.5% to arrive at the amount eligible for qualified
dividend income and 28.3% for the corporate dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will
be the amounts you are to use on your federal income tax return and will differ
from the amounts which we must report for the Fund's fiscal year ended October
31, 2007.

                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 0.5%. Class C shares
are sold with no initial sales charge, are subject to a CDSC of 1% if redeemed
within one year of purchase and have an annual 12b-1 fee of 0.5%. Performance
figures reflect certain fee waivers and/or expense limitations, without which
total returns may have been lower. These fee waivers and/or expense limitations
are contractual and may be modified or terminated only with the approval of the
Board of Trustees. The Manager may recoup the amount of certain management fee
waivers or expense reimbursements from the Fund pursuant to the contract if such
action does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which the Manager
incurred the expense. Prior to 9/1/98, performance for Class C shares includes
the historical performance of Class B shares adjusted to reflect the applicable
sales charge (or CDSC), fees, estimated expenses and fee waivers/expense
limitations of Class C shares upon initial offer. Unadjusted, the performance
shown for the newer class of shares might have been lower.

 6   MainStay Tax Free Bond Fund


COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY TAX FREE BOND FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

 8   MainStay Tax Free Bond Fund


PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers John Fitzgerald, CFA, and Laurie
Walters, CFA, of MacKay Shields LLC

HOW DID MAINSTAY TAX FREE BOND FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Tax Free Bond Fund returned 1.12% for
Class A shares, 0.86% for Class B shares and 0.86% for Class C shares for the 12
months ended October 31, 2007. All share classes underperformed the 1.47% return
of the average Lipper(1) general municipal debt fund and the 2.91% return of the
Lehman Brothers(R) Municipal Bond Index(2) for the 12 months ended October 31,
2007. The Lehman Brothers(R) Municipal Bond Index is the Fund's broad-based
securities-market index. See page 5 for Fund returns with sales charges.

WHAT FACTORS IN THE MUNICIPAL BOND MARKET AFFECTED THE FUND DURING THE 12-MONTH
REPORTING PERIOD?

Yields on shorter-term municipal bonds fell during the reporting period, while
yields on longer-term municipal bonds rose, causing the municipal yield curve to
steepen. At the long end, higher yields suggested that investors buying duration
were demanding higher compensation to offset rising inflation. At the short end,
lower yields suggested that investors were trying to anticipate Federal Open
Market Committee cuts in the targeted federal funds rate. Credit dislocations
over the summer caused active buyers of longer-maturity municipals, such as
hedge funds and foreign banks, to reduce their exposure to the market. All told,
the spread, or yield differential, between two-year and 30-year municipal bonds
widened by 50 basis points to 110 basis points by the end of October 2007. (A
basis point is one-hundredth of a percentage point.)

During the reporting period, municipal bond issuance surged to a record $428
billion, an increase
of 16.9% over the prior fiscal year. Relatively low interest rates gave issuers
a strong incentive to
come to market.

WHAT WAS THE FUND'S DURATION STRATEGY DURING THE REPORTING PERIOD?

Although tactical duration adjustments during the first half of the reporting
period were helpful, the Fund's overall duration strategy detracted from
performance. In December and January, the Fund's shorter duration relative to
the Lehman Brothers(R) Municipal Bond Index was helpful as interest rates rose.
In February, a modestly longer-than-benchmark duration was beneficial as
interest rates fell. A shorter-than-benchmark duration during August and
September, however, detracted from performance, as investors pursued
higher-quality securities for longer than we anticipated. Because the market
appeared overextended, the Fund ended the reporting period with a duration that
was modestly shorter than that of the Lehman Brothers(R) Municipal Bond Index.

WHAT POSITIONING DECISIONS AFFECTED THE FUND'S PERFORMANCE?

The Fund emphasized longer-maturity municipal bonds, which underperformed
shorter-maturity issues, so the Fund's yield-curve positioning detracted from
performance. During the reporting period, we reduced exposure to five-year
maturities in favor of 15-year and longer maturities for their incremental yield
and greater performance potential.

The Fund's position in Tennessee Energy Acquisition gas-prepay bonds backed by
Goldman Sachs counterparty ratings detracted from the Fund's performance. Credit
spreads widened in this sector, as investors grew increasingly concerned that
credit deterioration in subprime mortgages would have a negative impact on
brokerage earnings. Since we had confidence that Goldman Sachs remained
financially sound, the Fund continued to hold the Tennessee bonds.

On the positive side, the Fund benefited from issue selection. Exposure to
several higher-coupon callable bonds that were prerefunded during the reporting
period boosted the Fund's returns.(3)

WERE THERE SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

We sought to add incremental yield in sectors such as health care that offered
appropriate compensation for any additional risk. We purchased a Hillsborough,
Florida, issue for the expansion of Tampa General Hospital. The hospital has
been consistently profitable and serves a growing area.


Funds that invest in bonds are subject to interest rate, credit and inflation
risk and can lose principal value when interest rates rise. A portion of income
may be subject to state and local taxes or the alternative minimum tax. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund. The Fund may experience a
portfolio turnover rate of more than 100% and may generate taxable short-term
capital gains.

We added California State general obligations that offered a concession to the
market because of a multibillion dollar issuance. We also increased the Fund's
holdings in tobacco-settlement bonds as risk premiums aligned more closely with
foreseeable legal risks. In October, we added Buckeye, Ohio, Tobacco Settlement
bonds to the Fund. This asset-backed security receives payments from tobacco
manufacturers based upon their Master Settlement Agreement with the majority of
state attorneys general. Risk premiums widened to accommodate the $5.5 billion
offering, the largest tobacco-settlement issue to date.

We reduced exposure to industrial development bonds, water and sewer bonds and
prerefunded issues because they offered little in terms of incremental yield in
comparison with other credits. We also selectively reduced the Fund's exposure
to issues from Massachusetts, New York and Pennsylvania when relatively low
supply in these states made the bonds attractive sale candidates. We also
reduced the Fund's exposure to issues from New York City, as risk premiums were
narrow and we were concerned that difficulties in the financial markets could
affect anticipated revenues.

We sold the Fund's position in Charter Mac Equity Issuer Trust because credit
spreads had narrowed and we were concerned about the company's increased
leverage.

Early in the reporting period, we liquidated the Fund's position in Main Street,
Georgia Natural Gas backed by Merrill Lynch's counterparty rating, since Merrill
Lynch had expanded more aggressively into the subprime mortgage area with the
acquisition of First Franklin Financials. The Fund had no direct exposure to
subprime residential mortgages and the impact of the shakeout in subprime
lending on the Fund's performance during the reporting period was minimal.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2007, the Fund was overweight relative to the Lehman
Brothers(R) Municipal Bond Index in education, health care and transportation
bonds. As of the same date, the Fund was underweight in prerefunded bonds,
electric bonds and lease revenue bonds and neutrally weighted in
tobacco-settlement bonds.

3. Prerefunding or advance refunding is a procedure in which a bond issuer
   floats a second bond at a lower interest rate and the proceeds from the sale
   of the second bond are safely invested, usually in Treasury securities,
   which, in turn, are held in escrow collateralizing the first bond. Given that
   the advance refunded bonds become, essentially, fully tax-exempt U.S.
   Treasury securities and no longer represent the credit risk profile of the
   original borrower, they often increase in value--sometimes significantly.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Tax Free
Bond Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. Class A shares are offered at net asset value
per share plus an initial sales charge. No sales charge applies on investments
of $1 million or more (and certain other qualified purchases) in Class A shares,
but a contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within up to
six years of purchase of Class B shares and a 1% contingent deferred sales
charge may be imposed on redemptions made within one year of purchase of Class C
shares. As approved by the Board of Trustees in 1997, Class B shares convert to
Class A shares eight years after the date they were purchased. The three classes
of shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions except that Class
B and Class C shares are subject to higher distribution fee rates than Class A
shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to provide a high level of current income
free from regular federal income tax, consistent with the preservation of
capital.

The ability of issuers of debt securities held by the Fund to meet their
obligations may be affected by economic developments in a specific industry or
region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business. Futures contracts are valued at the last posted settlement price
on the market where such futures are primarily traded.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income monthly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the

 20   MainStay Tax Free Bond Fund


trade date. Realized gains and losses on security transactions are determined
using the identified cost method. Interest income is accrued as earned using the
effective interest rate method. Discounts and premiums on securities purchased,
other than short-term securities, for the Fund are accreted and amortized,
respectively, on the effective interest rate method over the life of the
respective securities or, in the case of a callable security, over the period to
the first date of call. Discounts and premiums on short-term securities are
accreted and amortized, respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 22) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a securities
index. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. The Fund invests in U.S. Treasury futures
contracts to gain full exposure to changes in bond market prices to fulfill its
investment objective. The Fund may enter into contracts for the future delivery
of debt securities in order to attempt to protect against the effect of adverse
changes in interest rates, to lengthen or shorten the average maturity or
duration of the Fund's portfolio or to try to enhance the Fund's returns.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.

(H) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.60% on assets up to $1.0 billion and 0.55% on

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

assets in excess of $1.0 billion. NYLIM has contractually agreed to waive its
management fee by 0.15% to 0.45% on assets up to $1.0 billion and 0.40% on
assets in excess of $1.0 billion which is not recoupable.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 0.89%; Class B, 1.14%; and Class C, 1.14%. This expense
limitation may be modified or terminated only with the approval of the Board of
Trustees. NYLIM may recoup the amount of any management fee waivers or expense
reimbursements from the Fund pursuant to the agreement if such action does not
cause the Fund to exceed existing expense limitations and the recoupment is made
within three years after the year in which NYLIM incurred the expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $1,452,082 and waived its fees in the amount of $405,365 of which
$42,343 is recoupable.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
        OCTOBER 31,
 2008*     2009      2010      TOTAL
                     
$30,280   $91,353   $42,343   $163,976
- --------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
0.89% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 9 on page
24).

The total dues associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Tax Free Bond Fund was $35,010. Additional
payments were made by affiliates relating to the shareholder trading matters.
Further discussion regarding these payments by affiliates can be found below in
the footnote relating to "Other Matters."

(C) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act.

Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.25% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $19,010 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $63, $28,930 and $779, respectively, for the year ended October 31,
2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is

 22   MainStay Tax Free Bond Fund


responsible. Transfer agent expenses incurred by the Fund, for the year ended
October 31, 2007, amounted to $229,361.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>
                                               
Class A                                    $52,847   0.0*%
- ----------------------------------------------------------
Class C                                        107   0.0*
- ----------------------------------------------------------
</Table>

* Less than one-tenth of a percent.

(H) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $9,047.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $50,868 for the year ended
October 31, 2007.
NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis
were as follows:

 --------------------------------------------------------------------------
</Table>

The difference between book-basis and tax basis unrealized appreciation is
primarily due to tax treatment of futures transactions.

The other temporary differences are primarily due to distribution payables.

The following table discloses the current year reclassifications between
accumulated undistributed net investment income, accumulated net realized loss
on investments and additional paid-in-capital, arising from permanent
differences; net assets at October 31, 2007 are not affected.

<Table>

    $208,491       $3,833,473      $(4,041,964)
 -----------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to capital loss
carryforwards expiring and sale of partnership investments.

At October 31, 2007, for federal income tax purposes, capital loss carryforwards
of $24,048,576 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

 -------------------------------------------
                              $24,049
 -------------------------------------------
</Table>

The Fund utilized $921,665 of capital loss carryforwards during the year ended
October 31, 2007.

The Fund had $4,041,964 of capital loss carryforwards that expired during the
year ended October 31, 2007.

The tax character of distributions paid during the years ended October 31, 2007
and October 31, 2006, shown in the Statement of Changes in Net Assets, was as
follows:

requests. These funds pay a commitment fee, at an annual rate of .060% of the
average commitment amount, regardless of usage, to The Bank of New York, which
acts as agent to the syndicate. Such commitment fees are allocated among the
funds based upon net assets and other factors. Interest on any revolving credit
loan is charged based upon the Federal Funds Advances rate. There were no
borrowings made or outstanding on the line of credit during the year ended
October 31, 2007.
NOTE 7--PURCHASES AND SALES OF SECURITIES (IN 000'S):

NOTE 9--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund

 24   MainStay Tax Free Bond Fund


shareholders over the period from 1999 to 2003 may have had on the funds. As a
result of this review, in December 2005, NYLIM made payments totaling $5.882
million to nine MainStay funds. The amount paid to the MainStay Tax Free Bond
Fund was $50,000. NYLIM has reimbursed or paid all expenses relating to the
Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

NOTE 11--RECENT DEVELOPMENTS:

On May 21, 2007, the United States Supreme Court agreed to hear an appeal in
Department of Revenue of Kentucky v. Davis, a case concerning the validity of
statutes that create a state tax exemption for interest from municipal
securities. The Kentucky Court of Appeals had held that Kentucky's statute,
which provided an exemption for interest earned on municipal securities of
Kentucky issuers while taxing interest earned on municipal securities of issuers
in other states, violated the Interstate Commerce Clause of the United States
Constitution. If the Supreme Court were to adopt the reasoning of the Kentucky
Court of Appeals, its decision would affect the state tax status of fund
distributions. It is unclear how such a decision would affect the market for
municipal securities, but it could adversely affect the value of securities held
by the fund, and therefore of the fund's shares. Such a decision could also
prompt legislation at the state level that would have further impacts upon the
taxability of fund distributions and upon the market for municipal securities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Tax Free Bond Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years in the four-year period then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Tax Free Bond Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years in the four-year period then ended, in
conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, underperformance when compared
over several time periods with groupings of funds having similar mandates and
the Fund's recent improvement in investment performance over the short term.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement, and from the overall relationship with
the Trust, was low. The Trustees considered other benefits that the Manager and
its affiliates receive from the relationship with the Trust, including benefits
that NYLIFE Distributors and MainStay Shareholder Services receive in exchange
for services they provide to the Funds, and certain benefits from soft dollar
arrangements. The Trustees acknowledged certain benefits to the reputation of
the Manager and the Trust from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement a
contractual breakpoint that would reduce the Fund's management fee at asset
levels above the breakpoint, and the fact that the breakpoint was intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund not reached the asset level at which the breakpoint would reduce the Fund's
management fee rate. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses

                                                    www.mainstayfunds.com     27


the Manager must reimburse to the Fund rather than directly benefiting the Fund
by reducing its net expenses. The Trustees considered information about transfer
agency expenses and their effect on the Fund's overall expenses. They considered
that, across the Trust (though not every series or share class), gross transfer
agency fees tended to be relatively high and, therefore, adversely affected
gross expense ratios. Noting that the Trust historically permitted smaller
investor accounts, the Trustees considered measures that had been recently
implemented that were intended to increase the average size of shareholder
accounts, including generally higher investment minimums and small account fees,
and the Trustees considered potential benefits to the Manager and its affiliates
arising from such measures.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including separate institutional
accounts having investment strategies similar to that of the Fund, and took
account of explanations and other information relating to the fees and expenses
of those other funds and accounts. The Trustees considered the current and
proposed contractual and net management fees, its anticipated gross and net
expense ratio, and various components of the expense ratio, in comparison to
other funds in comparison groupings. The Trustees generally acknowledged the
historical relationships among the Manager, the Subadvisor and the Trust and the
likely difficulties in implementing an alternative to the investment management
arrangement between the Trust and the Manager. The Trustees noted the Manager's
agreement to continue to waive a certain portion of its management fee and
maintain the existing contractual limitation on the Fund's net expenses.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Performance figures reflect
certain fee waivers and/or expense limitations, without which total returns may
have been lower. These fee waivers and/or expense limitations are contractual
and may be modified or terminated only with the approval of the Board of
Trustees. The Manager may recoup the amount of certain management fee waivers or
expense reimbursements from the Fund pursuant to the contract if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which the Manager
incurred the expense. Prior to 9/1/98 (for Class C shares) and 12/31/03 (for
Class I shares), performance for Class C and Class I shares includes the
historical performance of Class B shares adjusted to reflect the applicable
sales charge (or CDSC), fees, estimated expenses and fee waivers/expense
limitations of Class C and Class I shares upon initial offer. Unadjusted, the
performance of the newer classes of shares might have been lower.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY TOTAL RETURN FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Edmund C. Spelman, Richard A. Rosen,
CFA, Joseph Portera and Gary Goodenough of MacKay Shields LLC

HOW DID MAINSTAY TOTAL RETURN FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE 12 MONTHS ENDED OCTOBER 31, 2007?

Excluding all sales charges, MainStay Total Return Fund returned 12.18% for
Class A shares, 11.37% for Class B shares and 11.33% for Class C shares for the
12 months ended October 31, 2007. Over the same period, the Fund's Class I
shares returned 12.65%. All share classes underperformed the 13.51% return of
the average Lipper(1) mixed-asset target allocation growth fund and the 15.03%
return of the Russell 1000(R) Index(2) for the 12 months ended October 31, 2007.
The Russell 1000(R) Index is the Fund's broad-based securities-market index. See
pages 5 and 6 for Fund returns with sales charges.

DURING THE REPORTING PERIOD, WHICH SECTORS IN THE EQUITY PORTION OF THE FUND
WERE THE STRONGEST PERFORMERS AND WHICH SECTORS WERE PARTICULARLY WEAK?

Effective stock selection in the energy, materials and financials sectors made
the greatest positive contributions to the Fund's results relative to the
Russell 1000(R) Index. The equity sectors that detracted the most from the
Fund's relative performance were consumer discretionary and industrials.

DURING THE REPORTING PERIOD, WHICH STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE
FUND'S PERFORMANCE AND WHICH STOCKS DETRACTED?

During the reporting period, we established a new position in Southern Copper,
which produces copper and operates mining, smelting and refining facilities, and
a new position in National Oilwell Varco, an exploration and production services
and equipment company that experienced increased demand largely because of
rising oil prices. Both of these stocks were among the strongest contributors to
the Fund's performance. Apple, another major contributor, benefited from strong
sales of its existing products and from the company's entry into the cellular
phone handset market.

Financial services and retail holdings were the greatest detractors from
performance in the equity portion of the Fund. First Marblehead, which provides
services for private education loans, saw its share price decline as investors
worried about deterioration in the credit markets and new entrants into the
education-loan market. Merrill Lynch shares declined because of the company's
exposure to collateralized debt obligations and mortgage-backed securities. J.C.
Penney's shares fell on weaker-than-expected sales and on growing concerns about
consumer spending.

WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Strong performers Southern Copper and National Oilwell Varco were the most
significant additions during the reporting period. The Fund also initiated a
position in oil sands producer Suncor Energy during the reporting period, and it
advanced from the time of purchase through the end of October 2007.

We eliminated the Fund's positions in a number of industrials stocks, such as
Danaher, which designs and manufactures industrial and consumer products;
Federal Express, a worldwide express delivery company; and United Technologies,
which provides high-technology products and support services to customers in the
aerospace and building industries. We also eliminated some of the Fund's retail
holdings, including a sizeable position in home-improvement retailer Lowe's.


High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher- quality debt securities
and may be subject to greater price volatility. The Fund may invest in
derivatives, which may increase the volatility of the Fund's net asset value and
may result in a loss to the Fund. The principal risk of investing in value
stocks is that they may never reach what the portfolio manager believes is their
full value or that they may even go down in value. The principal risk of growth
stocks is that investors expect growth companies to increase their earnings at a
certain rate that is generally higher than the rate expected for nongrowth
companies. If these expectations are not met, the market price of the stock may
decline significantly, even if earnings showed an absolute increase. The Fund
may experience a portfolio turnover rate of more than 100% and may generate
taxable short-term capital gains. Funds that invest in bonds are subject to
credit, inflation and interest-rate risk and can lose principal value when
interest rates rise.

HOW DID YOU POSITION THE BOND PORTION OF THE FUND DURING THE REPORTING PERIOD?

With home prices no longer rising and with mortgage-lending standards
tightening, a substantial rise in mortgage defaults appeared inevitable. Leaders
in the packaging of subprime mortgages into collateralized debt obligations,
such as Lehman Brothers and Bear Stearns, saw their corporate bond spreads(3)
widen dramatically. These firms were soon joined by other financial behemoths,
such as Merrill Lynch and Citigroup. Fortunately, the Fund's exposure to
corporate bonds of these financial services companies was quite modest. These
bonds also had minimal impact on the Fund's performance owing to their short
duration(4) and their fixed-rate structure. Adjustable-rate collateral was the
hardest hit segment of the debt market during the reporting period, as the
expectation of higher delinquencies pushed interest rates on these mortgage
securities upward. The Fund had minimal exposure to adjustable-rate collateral,
so there was no negative impact on the Fund.

DID THE FUND'S BOND SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

The Fund benefited from the decision to reduce exposure to investment-grade
credit early in July, as well as the Fund's holdings in convertible bonds. The
Fund's convertible bond holdings had rallied strongly on the back of U.S.
equity-market performance during the first part of the reporting period.
However, sensing headwinds blowing toward risky assets, we later sold the Fund's
convertible bonds and corporate debentures in favor of U.S. Treasury securities
and cash. In doing so, we not only increased the Fund's weighting in Treasurys,
but we also slightly increased the duration of the bond portion of the Fund.
This modestly longer duration helped the Fund's performance. During the
reporting period, we modestly reduced the Fund's weighting in emerging-market
bonds. Still, the Fund maintained an overweight position in emerging-market
bonds, which boosted the Fund's relative performance.


3. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The term may also refer to the difference in yield between two specific
   securities or types of securities at a given time.
4. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

The opinions expressed are those of the portfolio managers as of the date of

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Total
Return Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on December 29, 1987. Class C shares
commenced on September 1, 1998. Class I shares commenced on January 2, 2004.
Class A shares are offered at net asset value per share plus an initial sales
charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within up to six years of purchase of Class B
shares and a 1% contingent deferred sales charge may be imposed on redemptions
made within one year of purchase of Class C shares. Class I shares are not
subject to a sales charge. As approved by the Board of Trustees in 1997, Class B
shares convert to Class A shares eight years after the date they were purchased.
The four classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A shares under a distribution plan pursuant to Rule 12b-1 under
the 1940 Act. Class I shares are not subject to a distribution or service fee.

The Fund's investment objective is to realize current income consistent with
reasonable opportunity for future growth of capital and income.

The Fund invests in foreign securities, which carry certain risks that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, as defined in Note 3,
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager to be
representative of market values, at the regular close of trading of the New York
Stock Exchange (generally 4:00 p.m. Eastern time) on each day the Fund is open
for business.

Equity securities are valued at the latest quoted sales prices as of the close
of trading on the New York Stock Exchange on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Options contracts are valued at the last posted settlement price on the market
where such options are principally traded. Investments in mutual funds are
valued at their net asset value as of the close of the New York Stock Exchange
on the date of valuation.

Loans are valued at the average of bid quotations obtained from a pricing
service. The Trust has engaged an independent pricing service to provide market
value quotations from dealers in loans. As of October 31, 2007, 100% of total
investments in loans were valued based on prices from such services.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is

 30   MainStay Total Return Fund


temporarily closed at a time when, under normal conditions, it would be open. At
October 31, 2007, the Fund held securities with a value of $1,778,759 that were
valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3, conclude that such events may have
effected the accuracy of the last price reported on the local foreign market,
the Manager or Subadvisor may, pursuant to procedures adopted by the Fund,
adjust the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income quarterly and distributions of net realized capital and
currency gains, if any, annually. All dividends and distributions are reinvested
in shares of the Fund, at net asset value, unless the shareholder elects
otherwise. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from generally
accepted accounting principles in the United States of America. Permanent
book/tax differences relating to income and gains are reclassified amongst
undistributed net investment income, accumulated net realized gain or loss and
paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage-backed securities. Dividend
income is recognized on the ex-dividend date and interest income is accrued as
earned using the effective interest rate method. Discounts and premiums on
securities purchased, other than short-term securities, for the Fund are
accreted and amortized, respectively, on the effective interest rate method over
the life of the respective securities or, in the case of a callable security,
over the period to the first date of call. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 34) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are canceled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the price of the underlying security or foreign currency
increase. By writing a covered put option, the Fund, in exchange for the
premium, accepts the risk of a decline in the market value of the underlying
security or foreign currency below the exercise price. A call option may be
covered by the call writer's owning the underlying security throughout the
option period. A call option may also be covered by the call writer's
maintaining liquid

                                                    www.mainstayfunds.com     31

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

assets valued at greater than the exercise price of the call written. When
writing a covered call option, the Fund, in return for the premium on the
option, gives up the opportunity to profit from a price increase in the
underlying securities above the exercise price, but, as long as the obligation
as the writer continues, has retained the risk of loss should the price of the
underlying security decline. After writing a put option, the Fund may incur a
loss equal to the difference between the exercise price of the option and the
sum of the market value of the underlying security plus the premium received
from the sale of the option.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option. (See Note 5 on page 35.)

(H) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate ("LIBOR").

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. For example, the Fund may be
contractually obligated to receive approval from the agent bank and/or borrower
prior to the sale of these investments.

The Fund assumes the credit risk of the borrower, the selling participant and
any other persons interpositioned between the Fund and the borrower
("intermediate participants"). In the event that the borrower, selling
participant or intermediate participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
borrower. At any point in time, up to the maturity date of the issue, the
borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(I) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
rates last quoted by any major U.S. bank at the following dates:


(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(J) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the Portfolio of Investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, the Fund forgoes principal and interest paid on the securities. The Fund
is compensated by the difference between the current sales price and the forward
price for the future as well as by the earnings on the cash proceeds of the
initial sale. MDRs may be renewed without physical delivery of the securities
subject to the contract. The Fund maintains liquid assets from its portfolio
having a value not less than the repurchase price, including accrued interest.
MDR transactions involve certain risks, including the risk that the MBS returned
to the

 32   MainStay Total Return Fund


Fund at the end of the roll, while substantially similar, could be inferior to
what was initially sold to the counterparty.

(K) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(L) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. The Fund may not
have the right to demand that such securities be registered. Disposal of these
securities may involve time-consuming negotiations and expenses and it may be
difficult to obtain a prompt sale at an acceptable price. (See Note 5 on page
35.)

(M) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.64% on assets up to $500 million and 0.60% on assets in
excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.19%; Class B, 1.94%; Class C, 1.94% and Class I, 0.79%.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. NYLIM may recoup the amount of any management fee waivers
or expense reimbursements from the Fund pursuant to the agreement if such action
does not cause the Fund to exceed existing expense limitations and the
recoupment is made within three years after the year in which NYLIM incurred the
expense.

For the year ended October 31, 2007, NYLIM earned fees from the Fund in the
amount of $4,346,669 and waived its fees in the amount of $575,951.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
                      OCTOBER 31,
 2008*       2009         2010            TOTAL
                           
$177,401  $1,037,949    $575,951    $1,791,301
- -----------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.19% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 11 on
page 37.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $79,841. Additional payments were
made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.
Pursuant to the Class A Plan, the Distributor receives a monthly distribution
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A shares, which is an expense of the Class A shares of the Fund
for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly distribution fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Plans provide that the Class B and Class
C shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B and Class C shares of the Fund.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $38,594 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $3,773, $177,889 and $100, respectively, for the year ended October
31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $2,172,212.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

NOTE 11--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to

 36   MainStay Total Return Fund


nine MainStay funds. The amount paid to the MainStay Total Return Fund was
$102,000. NYLIM has reimbursed or paid all expenses relating to the Board of
Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 12--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Fund, a minimum threshold for financial statement recognition of the
benefit of positions taken in filing tax returns (including whether an entity is
taxable in a particular jurisdiction), and requires certain expanded tax
disclosures. The Interpretation becomes effective for the Fund's 2008 fiscal
year, 2007, and is to be applied to all open tax years as of the date of
effectiveness. Based on Management's analysis, the determination has been made
that the adoption of the interpretation on November 1, 2007, did not have an
impact on the Fund's financial statements upon adoption. Management continually
reviews the Fund's tax positions and such conclusions under the Interpretation
based on factors, including, but not limited to, ongoing analyses of tax laws,
regulations and interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Total Return Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Total Return Fund of The MainStay Funds as of October 31, 2007, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years or periods in the four-year period then ended,
in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's underperformance over
various time periods considered relative to the investment performance of funds
having similar investment mandates, and the Manager's assurance that it would
monitor the Fund's performance closely.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund was moderate,
and from the overall relationship with the Trust was low. The Trustees
considered other benefits that the Manager and its affiliates receive from the
relationship with the Trust, including benefits that NYLIFE Distributors and
MainStay Shareholder Services receive in exchange for services they provide to
the Funds, and certain benefits from soft dollar arrangements. The Trustees
acknowledged certain benefits to the reputation of the Manager and the Trust
from their association with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered

                                                    www.mainstayfunds.com     39


potential benefits to the Manager and its affiliates arising from such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints that would reduce the Fund's management fee at asset
levels above the breakpoints, and the fact that the breakpoints were intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees reviewed
information showing that the Fund's asset level had decreased over the past
several years but noted that the Fund's management fee rate had been reduced by
the breakpoint schedule applicable to the Fund. The Trustees reviewed
information about the potential effect of asset growth on Fund expenses, the
difficulty of forecasting its effect on the profitability of the Manager and its
affiliates, and the management fee breakpoints applicable to the Fund and
certain other funds. It was noted that, to the extent the Fund's gross expenses
currently were higher than its net expenses, the reduction of the Fund's gross
expenses through the achievement of economies of scale might benefit the Manager
by reducing the expenses the Manager must reimburse to the Fund rather than
directly benefiting the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees took account of the Manager's willingness to maintain the management
fee waiver and expense limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $53,968,910.

The dividends paid by the Fund during the fiscal year ended October 31, 2007,
should be multiplied by 22.8% to arrive at the amount eligible for qualified
dividend income, 64.6% for qualified interest income and 25.6% for the corporate
dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will

                    Message from the President
                    and
                    Annual Report
                    October 31, 2007


MESSAGE FROM
THE PRESIDENT

The 12-month period ended October 31, 2007, was a dynamic one for mutual fund
investors. U.S. equity markets generally advanced, with growth stocks out-
performing value stocks at all capitalization levels. Although past performance
is no guarantee of future results, international stocks as a whole provided even
stronger returns for U.S. investors.

The progress of the equity markets, however, was far from steady. In February,
weakness in Asian markets led to sharp price declines around the globe. The
correction caused many investors to reconsider whether China and other emerging
economies could sustain their rapid growth. Fortunately, strong
corporate-earnings reports and positive economic news helped the stock market
regain its footing.

In July and August, difficulties in the subprime-mortgage market led to another
stock-market correction. A number of high-profile mortgage originators either
closed their doors or were sold to larger entities. Other leading financial
services firms faced major write-offs because of subprime-mortgage exposure.

The Federal Open Market Committee (FOMC) took prompt action to increase
liquidity and stabilize the financial markets by lowering the discount rate and
the federal funds target rate during the reporting period. These Federal Reserve
moves helped calm investor concerns, and the stock market generally advanced
from August 16, 2007, the date of an unscheduled FOMC meeting, through the end
of October 2007.

Difficulties in the subprime-mortgage market led to a "flight to quality," or a
general movement toward fixed-income securities that carry lower risk. As demand
for short- and intermediate-term Treasury securities increased, yields fell
across much of the maturity spectrum. Yields rose, however, on 20-and 30-year
Treasury bonds, and the yield curve steepened during the 12-month reporting
period.

High-yield bonds rallied from November 2006 through May 2007. But in June and
July, the yield differences--or spreads--between high-yield bonds and comparable
Treasury securities began to widen. At the end of October 2007, these spreads
were wider than when the reporting period began, making high-yield securities
more attractive to investors willing to accept higher risk.

To help investors address the challenges of today's ever-changing markets, New
York Life Investment Management LLC provides access to seven institutional
investment boutiques, each with its own proprietary research and investment
culture. As advisors and subadvisors to MainStay Funds, these boutiques bring a
wealth of experience and market insight to our shareholders. The portfolio
managers of each MainStay Fund seek to consistently apply time-tested investment
principles across a wide variety of market environments.

The report that follows provides more specific information about the market
forces and investment decisions that affected your investment in MainStay Funds
from November 1, 2006, through October 31, 2007. Please read the report
carefully. As you do, bear in mind that this annual report reflects just a short
segment of your lifetime investment journey. We look forward to continuing to
work with you, wherever that journey may lead.

Sincerely,


/s/ STEPHEN P. FISHER

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect maximum applicable sales charges explained in this paragraph, change in
share price, and reinvestment of dividend and capital-gain distributions. The
graphs assume an initial investment of $10,000 and reflect the deduction of all
sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of
..25%. Class R1 and Class R2 shares are available only through
corporate-sponsored retirement programs, which include certain minimum program
requirements. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. These fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. The Manager may recoup the
amount of certain management fee waivers or expense reimbursements from the Fund
pursuant to the contract if such action does not cause the Fund to exceed
existing expense limitations and the recoupment

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY VALUE FUND
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2007, to October 31, 2007,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
2007, to October 31, 2007.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2007. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Richard A. Rosen, CFA, of MacKay Shields
LLC

HOW DID MAINSTAY VALUE FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK
DURING THE 12-MONTH REPORTING PERIOD?

Excluding all sales charges, MainStay Value Fund returned 12.46% for Class A
shares, 11.66% for Class B shares and 11.61% for Class C shares for the 12
months ended October 31, 2007. Over the same period, the Fund's Class I shares
returned 13.00%, Class R1 shares returned 12.89% and Class R2 shares returned
12.48%. With the exception of Class B and Class C shares, all share classes
outperformed the 12.21% return of the average Lipper(1) large-cap value fund for
the 12 months ended October 31, 2007. All share classes outperformed the 10.83%
return of the Russell 1000(R) Value Index,(2) the Fund's broad-based
securities-market index, for the 12-month reporting period. See page 5 for Fund
returns with sales charges.

WHICH FUND HOLDINGS WERE PARTICULARLY STRONG DURING THE REPORTING PERIOD?

As a group, financial stocks tended to underperform during the reporting period.
Fortunately, the Fund maintained an underweight position in the sector and
avoided most of the stocks that experienced major corrections because of credit
or subprime-mortgage exposure. As a result, financials provided a significant
positive contribution to the Fund's relative performance. The Fund's positions
in Bank of New York, Goldman Sachs and Prudential Financial bucked the trend and
performed well. We reduced the Fund's position in Goldman Sachs as its shares
approached our price target.

In the information technology sector, Nokia Oyj's shares more than doubled
during the reporting period as the company gained market share, particularly in
emerging markets. We trimmed the Fund's position in Nokia Oyj as its shares
approached our price target. We added to the Fund's positions in Intel and IBM
during the reporting period, and both stocks recorded substantial gains.

Higher energy prices helped several of the Fund's energy holdings, including
drillers GlobalSantaFe, Diamond Offshore Drilling and Transocean. Each of these
stocks rose sharply, and Transocean's acquisition bid for GlobalSantaFe
highlighted significant asset value in the energy equipment & services industry.
We reduced the Fund's holdings in Diamond Offshore Drilling and GlobalSantaFe
and eliminated the Transocean position as the stocks approached their respective
price targets.

Other positive performers included Honeywell International, CVS Caremark, Teck
Cominco, Teva Pharmaceuticals and KOS Pharmaceuticals. Honeywell demonstrated
strong earnings growth and initiated a new share buyback program. We reduced the
Fund's position in the stock near our price target. Pharmacy and front-store
sales trends at CVS Caremark remained positive and the integration of Caremark
into the combined company proceeded well. We added to the Fund's CVS Caremark
position in the middle of the reporting period. Teva Pharmaceuticals benefited
from good trends in the generic drug industry. We added to the Fund's Teva
Pharmaceuticals position early in the reporting period and trimmed the position
late in the period. KOS Pharmaceuticals' shares rose when the company became the
target of an acquisition bid by Abbott Laboratories.

WHICH POSITIONS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING
PERIOD?

In the financials sector, Genworth Financial, Freddie Mac, Capital One Financial
and PMI Group all detracted from the Fund's performance. Our assessment of the
negative shift in company fundamentals led us to eliminate PMI Group and reduce
the Fund's positions in the other companies.

Additional stocks that detracted from the Fund's performance included Home
Depot, Lowe's, The Gap and Amgen. Sales at Home Depot and Lowe's suffered from
the housing downturn. We reduced the Fund's position in Home Depot and added to
Lowe's. We sold the Fund's entire position in The Gap, as the company continued
to struggle with its fashion initiatives. Amgen, a new position during the
reporting period, declined on concerns about the safety of one of the company's
key drug families.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

In addition to the transactions we've already mentioned, we added oil sands
producer Suncor Energy to the Fund, and its shares rose sharply from the time of
purchase through the end of October. Teck Cominco, another addition during the
reporting period, benefited from high copper and zinc prices.


The principal risk of investing in value stocks is that they may never reach
what the portfolio manager believes is their full value or they may even go down
in value. The Fund may experience a portfolio turnover rate of more than 100%
and may generate taxable short-term gains.

Several information technology stocks showed poor performance and were
eliminated from the Fund. We sold all of the Fund's holdings in Motorola and
Advanced Micro Devices. Both companies were losing market share, and we no
longer felt that their reward potential justified the inherent risks.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2007, the Fund was overweight relative to the Russell 1000(R)
Value Index in health care, information technology, materials and consumer
staples. On the same date, the Fund was underweight in consumer discretionary,
financials, industrials, telecommunication services, energy and utilities.

NOTES TO FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay Value
Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares. Class A shares commenced on
January 3, 1995. Class B shares commenced on May 1, 1986. Class C shares
commenced on September 1, 1998. Class I shares, Class R1 shares and Class R2
shares commenced on January 2, 2004. Class A shares are offered at net asset
value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within up to six years of purchase of Class B shares and a 1% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I, Class R1 and Class R2 shares are not
subject to a sales charge. As approved by the Board of Trustees in 1997, Class B
shares convert to Class A shares eight years after the date they were purchased.
The six classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B and Class C shares are subject to higher distribution fee
rates than Class A and Class R2 shares under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act. Class I and Class R1 shares are not subject to a
distribution or service fee. Class R1 and Class R2 shares are authorized to pay
to New York Life Investment Management LLC, its affiliates, or third-party
service providers, as compensation for services rendered to shareholders of
Class R1 or Class R2 shares, a shareholder service fee.

The Fund's investment objective is to realize maximum long-term total return
from a combination of capital growth and income.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on each day the Fund is open for business
("valuation date"). Securities that are not traded on the valuation date are
valued at the mean of the latest quoted bid and asked prices. Prices normally
are taken from the principal market in which each security trades. Options
contracts are valued at the last posted settlement price on the market where
such options are principally traded. Investments in mutual funds are valued at
their net asset value as of the close of the New York Stock Exchange on the date
of valuation.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature 60 days or less are valued at amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board of Trustees to represent fair
value. Equity and non-equity securities which may be valued in this manner
include, but are not limited to: a security the trading for which has been
halted or suspended; a debt security that has recently gone into default and for
which there is not a current market quotation; a security of an issuer that has
entered into a restructuring; a security that has been de-listed from a national
exchange; a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's investment adviser or sub-adviser (if applicable), reflect the security's
market value; a security where the trading on that security's principal market
is temporarily closed at a time when, under normal conditions, it would be open.
At October 31, 2007, the Fund did not hold securities that were valued in such a
manner.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
of net investment income and distributions of net realized capital and currency
gains, if any, annually. All dividends and distributions are reinvested in
shares of the

 22   MainStay Value Fund


Fund, at net asset value, unless the shareholder elects otherwise. Dividends and
distributions to shareholders are determined in accordance with federal income
tax regulations and may differ from generally accepted accounting principles in
the United States of America. Permanent book/tax differences relating to income
and gains are reclassified amongst undistributed net investment income,
accumulated net realized gain or loss and paid-in-capital.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term securities, for the Fund are accreted and
amortized, respectively, on the effective interest rate method over the life of
the respective securities or, in the case of a callable security, over the
period to the first date of call. Discounts and premiums on short-term
securities are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3 (C) on
page 24) are allocated to separate classes of shares pro rata based upon their
relative net assets value on the date the expenses are incurred. The expenses
borne by the Fund, including those of related parties to the Fund, are shown in
the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
accounting principles generally accepted in the United States of America,
management makes estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from those
estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are canceled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the price of the underlying security or foreign currency
increase. By writing a covered put option, the Fund, in exchange for the
premium, accepts the risk of a decline in the market value of the underlying
security or foreign currency below the exercise price. A call option may be
covered by the call writer's owning the underlying security throughout the
option period. A call option may also be covered by the call writer's
maintaining liquid assets valued at greater than the exercise price of the call
written. When writing a covered call option, the Fund, in return for the premium
on the option, gives up the opportunity to profit from a price increase in the
underlying securities above the exercise price, but, as long as the obligation
as the writer continues, has retained the risk of loss should the price of the
underlying security decline. After writing a put option, the Fund may incur a
loss equal to the difference between the exercise price of the option and the
sum of the market value of the underlying security plus the premium received
from the sale of the option.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(H) SECURITIES LENDING.  In order to realize additional income the Fund may lend
its securities to broker-dealers and financial institutions. The loans are
collateralized by cash or securities at least equal at all times to the market
value of the securities loaned. Collateral will consist of U.S. Government
securities, cash equivalents or irrevocable letters of credit. The Fund may bear
the risk of delay in recovery of, or loss of rights in, the securities loaned
should the borrower of the securities experience financial difficulty. The Fund
receives compensation for lending its securities in the form of fees or it
retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

during the term of the loan will be for the account of the Fund.

(I) INDEMNIFICATIONS.  In the normal course of business, the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote.
However, there can be no assurance that material liabilities related to such
obligations will not arise in the future which could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
"Manager") a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager. NYLIM provides offices and conducts clerical, recordkeeping and
bookkeeping services, and is responsible for the financial and accounting
records required to be maintained by the Fund. NYLIM also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and an indirect wholly-owned
subsidiary of New York Life, serves as subadvisor to the Fund and is responsible
for the day-to-day portfolio management of the Fund. Pursuant to the terms of a
Subadvisory Agreement between NYLIM and the Subadvisor, NYLIM pays for the
services of the Subadvisor.

The Fund is contractually obligated to pay NYLIM a monthly fee for services
performed and facilities furnished at an annual rate of the Fund's average daily
net assets as follows: 0.72% on assets up to $200 million, 0.65% on assets from
$200 million to $500 million and 0.50% on assets in excess of $500 million.

Effective March 1, 2007, NYLIM has entered into a written expense limitation
agreement under which it has agreed to waive a portion of the Fund's management
fee or reimburse the expenses of the appropriate class of the Fund so that the
class' total ordinary operating expenses (total annual operating expenses
excluding taxes, interest, litigation, extraordinary expenses, and brokerage and
other transaction expenses relating to the purchase or sale of portfolio
investments) do not exceed the following amounts of average daily net assets for
each class: Class A, 1.17%; Class B, 1.92%; Class C, 1.92%; Class I, 0.71%;
Class R1, 0.81% and Class R2, 1.06%. This expense limitation may be modified or
terminated only with the approval of the Board of Trustees. NYLIM may recoup the
amount of any management fee waivers or expense reimbursements from the Fund
pursuant to the agreement if such action does not cause the Fund to exceed
existing expense limitations and the recoupment is made within three years after
the year in which NYLIM incurred the expense. For the year ended October 31,
2007, the NYLIM earned fees from the Fund in the amount of $4,678,384 and waived
its fees in the amount of $320,473.

As of October 31, 2007, the amounts of waived fees that are subject to possible
recoupment by NYLIM, and the related expiration dates are as follows:

<Table>
<Caption>
                   OCTOBER 31,
        2008*                2009          2010          TOTAL
                                              

      $235,721             $907,175      $320,473      $1,463,369
- -----------------------------------------------------------------
</Table>

* The expense limitation agreement became effective in 2005 and the recoupments
  will start to expire in 2008.

Prior to March 1, 2007, NYLIM had an agreement in place under which it had
agreed to waive a portion of the Fund's management fee or reimburse the expenses
of the Fund so that the Fund's total ordinary operating expenses did not exceed
1.17% of the Fund's average daily net assets for its Class A shares. NYLIM also
applied an equivalent waiver or reimbursement, in an equal amount of basis
points, to the other share classes of the Fund.

State Street Bank & Trust Company ("SSBT"), One Lincoln Street, Boston,
Massachusetts, 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with NYLIM. These services include calculating
daily net asset values of the Fund, maintaining general ledger and sub-ledger
accounts for the calculation of the Fund's respective net asset values, and
assisting NYLIM in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, SSBT is compensated by
NYLIM.

(B) PAYMENTS FROM AFFILIATES.  NYLIM reimbursed or paid all expenses relating to
the Board of Trustees' review of certain shareholder trading matters as
described below in the footnote relating to "Other Matters." (See Note 10 on
page 27.)

The total costs associated with the Board of Trustees' review were approximately
$849,975 and included payments to certain third party service providers.

The amount that was reimbursed to the Fund was $73,953. Additional payments were
made by affiliates relating to the shareholder trading matters. Further
discussion regarding these payments by affiliates can be found below in the
footnote relating to "Other Matters."

(C) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a

 24   MainStay Value Fund


Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
Class A, Class B, Class C, and Class R2 shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Class A and Class R2 Plans, the Distributor receives a monthly
distribution fee from the Fund at an annual rate of 0.25% of the average daily
net assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly distribution fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
and Class C shares of the Fund. Class I and Class R1 shares are not subject to a
distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

In accordance with the Shareholder Services Plans for the Class R1 and Class R2
shares, the Manager has agreed to provide, through its affiliates or independent
third parties, various shareholder and administrative support services to
shareholders of the Class R1 and Class R2 shares. For its services, the Manager
is entitled to a Shareholder Service Fee accrued daily and paid monthly at an
annual rate of 0.10% of the average daily net assets attributable to the Class
R1 and Class R2 shares.

(D) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $54,741 for the year ended
October 31, 2007. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5,285, $195,585 and $1,731, respectively, for the year ended October
31, 2007.

(E) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services pursuant to which
it performs certain services for which NYLIM Service is responsible. Transfer
agent expenses incurred by the Fund, for the year ended October 31, 2007,
amounted to $1,972,340.

(F) SMALL ACCOUNT FEES.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts, effective March 1, 2007. Shareholders with an account
balance of less than $1,000 are charged an annual per account fee of $20
(assessed semi-annually).

(G) CAPITAL.  At October 31, 2007, New York Life and its affiliates held
beneficially shares of the Fund with the following values and percentages of net
assets as follows:

<Table>
                                                    
Class I                                        $14,652        13.7%
- ------------------------------------------------------------------
</Table>

(H) OTHER.  Pursuant to an Amended and Restated Management Agreement between the
Fund and NYLIM, the cost of legal services provided to the Fund by the Office of
the General Counsel of NYLIM are payable directly by the Fund. For the year
ended October 31, 2007, these fees, which are included in professional fees
shown on the Statement of Operations, were $28,547.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $102,434 for the year ended
October 31, 2007.

NOTE 4--FEDERAL INCOME TAX:

As of October 31, 2007, the components of accumulated gain/(loss) on a tax basis

NOTE 10--OTHER MATTERS:

As reported in response to requests for information by various regulators,
including the Securities and Exchange Commission ("SEC") and the New York State
Attorney General, and, as noted in the notes to the year-end 2004, 2005 and 2006
financial statements of each fund of the Trust, NYLIM was previously a party to
arrangements with certain registered representatives of broker-dealers relating
to the level of trading by clients of those registered representatives in shares
of certain funds of the Trust. All such arrangements were terminated by the
fourth quarter of 2003.

NYLIM and the Trustees of the Trust undertook a review of the possible dilutive
effects that transactions under those arrangements and certain other levels of
trading by Fund shareholders over the period from 1999 to 2003 may have had on
the funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.882 million to nine MainStay funds. The amount paid to the Mainstay
Value Fund was $374,000. NYLIM has reimbursed or paid all expenses relating to
the Board of Trustees' review of this matter.

In a separate matter, in 2004 the SEC raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to that fund's
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

NOTE 11--NEW ACCOUNTING PRONOUNCEMENTS:

In July 2006, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes," an
interpretation of FASB Statement No. 109 (the "Interpretation"). The
Interpretation

                                                    www.mainstayfunds.com     27

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

establishes for all entities, including pass-through entities such as the Fund,
a minimum threshold for financial statement recognition of the benefit of
positions taken in filing tax returns (including whether an entity is taxable in
a particular jurisdiction), and requires certain expanded tax disclosures. The
Interpretation becomes effective for the Fund's 2008 fiscal year, and is to be
applied to all open tax years as of the date of effectiveness. Based on
Management's analysis, the determination has been made that the adoption of the
interpretation on November 1, 2007, did not have an impact on the Fund's
financial statements upon adoption. Management continually reviews the Fund's
tax positions and such conclusions under the Interpretation based on factors,
including, but not limited to, ongoing analyses of tax laws, regulations and
interpretations, thereof.

In September 2006, FASB issued Statement on Financial Accounting Standards
(SFAS) No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of "fair value", sets out a framework for measuring
fair value and requires additional disclosures about fair value measurements.
SFAS No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of October 31, 2007, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the Fund's
financial statements. However, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain measurements
reported in the financial statements for a fiscal period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Value Fund ("the Fund"), one of
the funds constituting The MainStay Funds, as of October 31, 2007, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years or periods in the four-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2007, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Value Fund of The MainStay Funds as of October 31, 2007, the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and the financial highlights for
each of the years or periods in the four-year period then ended, in conformity
with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

The Board of Trustees of the Fund approved the renewal of the Fund's Management
Agreement with New York Life Investment Management LLC (the "Manager") and the
Subadvisory Agreement between the Manager and MacKay Shields LLC, a wholly-owned
indirect subsidiary of New York Life Investment Management Holdings LLC, an
affiliate of the Manager, (the "Subadvisor"), (each an "Agreement") at a meeting
held on May 22 and 23, 2007. In connection with the approval of each Agreement,
the Trustees reviewed a significant amount of a wide variety of information that
they had requested and received from the Manager and the Subadvisor, and data
and analysis from an outside data provider and a third party consultant. The
Trustees considered various industry trends and regulatory developments in their
deliberations. In considering approval of each Agreement, and in evaluating the
fairness of the compensation to be paid by the Fund, the Trustees met both as a
full Board and in executive session with no Interested Trustee present, in
advance of the meeting at which the Agreements were approved, and they
considered a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and the Subadvisor have provided historically to the Fund, and
also generally to other series of the Trust. Among other services, the Manager's
services have included investment management services, including monitoring and
evaluating the Subadvisor's investment program and investment results with
respect to the Fund, and the Subadvisor's compliance with the Fund's investment
policies and restrictions, and administrative services, including working with
other service providers of the Trust, maintaining certain Fund records,
providing office space, performing clerical and bookkeeping services for the
Fund, preparing Board materials and Fund filings, and otherwise managing the
Trust's operations. The Subadvisor is responsible for the day-to-day portfolio
management of the Fund, including determining the composition of assets of the
Fund and the timing of the Fund's execution of the purchase and sale of assets,
and its other services include, among other services, providing reports to the
Manager and reviewing certain aspects of Fund filings. The Trustees considered,
among other things, the Manager's and Subadvisor's management, personnel,
resources, operations and portfolio management capabilities. The Board reviewed
reports on the Subadvisor's brokerage practices, including with respect to best
execution of portfolio trades. The Trustees considered the Manager's supervision
of the Fund's service providers and its attention to the compliance program of
the Trust, the Manager, the Subadvisor and certain other service providers, as
well as the Subadvisor's attention to its compliance program. The Trustees noted
the generally favorable results of a third party review of the services and
communications that NYLIM Service Company LLC, an affiliate of the Manager and
the Subadvisor, has provided to Trust shareholders.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of funds in groups that the
Trustees concluded, in consultation with an outside data provider and a third
party consultant, were appropriate comparison groups for the Fund. The Board's
decision took account of, among other things, the Fund's generally mid-range
performance over the short term and slight underperformance over the longer term
relative to groupings of funds having similar mandates.

The Trustees considered the cost to the Manager of each Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods. In reviewing profitability information, the
Trustees reviewed, among other things, information about the allocation of
expenses among the Manager and its affiliates. The Trustees were provided
information that indicated that the profitability to the Manager and its
affiliates from the Management Agreement with respect to the Fund and from the
overall relationship with the Trust was low. The Trustees considered other
benefits that the Manager and its affiliates receive from the relationship with
the Trust, including benefits that NYLIFE Distributors and MainStay Shareholder
Services receive in exchange for services they provide to the Funds, and certain
benefits from soft dollar arrangements. The Trustees acknowledged certain
benefits to the reputation of the Manager and the Trust from their association
with each other.

The Trustees reviewed information about the compensation program for portfolio
managers employed by the Manager, including that the program was designed to
align portfolio manager compensation with investors' goals. The Trustees also
reviewed information about portfolio manager holdings in the Trust and generally
noted favorably those portfolio managers of the Trust who invest in portfolios
they manage.

The Trustees considered information about transfer agency expenses and their
effect on the Fund's overall expenses. They considered that, across the Trust
(though not every series or share class), gross transfer agency fees tended to
be relatively high and, therefore, adversely affected gross expense ratios.
Noting that the Trust historically permitted smaller investor accounts, the
Trustees considered measures that had been recently implemented that were
intended to increase the average size of shareholder accounts, including
generally higher investment minimums, and small account fees, and the Trustees
considered potential benefits to the Manager and its affiliates arising from
such measures.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund's assets, or the assets of the Trust
overall, increase. The Trustees noted, in particular, the plans of the Manager
and its affiliates for marketing and distributing the shares of the various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints that would reduce the Fund's management fee at asset
levels above the breakpoints, and the fact that the breakpoints were intended to
provide that shareholders would share in benefits from economies of scale
obtained through the growth in the Fund's assets. The Trustees noted that the
Fund's management fee rate had been reduced by the breakpoint schedule
applicable to the Fund. The Trustees reviewed information about the potential
effect of asset growth on Fund expenses, the difficulty of forecasting its
effect on the profitability of the Manager and its affiliates, and the
management fee breakpoints applicable to the Fund and certain other funds. It
was noted that, to the extent the Fund's gross expenses currently were higher
than its net expenses, the reduction of the Fund's gross expenses through the
achievement of economies of scale might benefit the Manager by reducing the
expenses the Manager must reimburse to the Fund rather than directly benefiting
the Fund by reducing its net expenses.

The Trustees considered information about services provided by other investment
advisers of funds having investment objectives and policies similar to the
Fund's. The Board received and reviewed, among other things, comparative data on
various types of Fund expenses. In considering the management fees paid by the
Fund, the Trustees evaluated factors such as the fees and expenses borne by
other registered funds in the market pursuing strategies generally similar to
the Fund's. The Trustees considered certain comparative data with respect to
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts having investment strategies similar to that
of the Fund, and took account of explanations and other information relating to
the fees and expenses of those other funds and accounts. The Trustees considered
the current and proposed contractual and net management fees, its anticipated
gross and net expense ratio, and various components of the expense ratio, in
comparison to other funds in comparison groupings. The Trustees generally
acknowledged the historical relationships among the Manager, the Subadvisor and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between the Trust and the Manager. The
Trustees took account of the Manager's willingness to maintain the management
fee waiver and expense limitation applicable to the Fund.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings, with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. This summary set out
above describes the most important, but not all, of the factors considered by
the Trustees in considering each Agreement. On the basis of their review, a
majority of the Trustees and a majority of the Non-Interested Trustees concluded
that each factor they considered, in the context of all the other factors they
considered, favored renewal of each Agreement, and it was the judgment of a
majority of the Trustees and a majority of the Non-Interested Trustees that
approval of each Agreement was in the best interests of the Fund and its
shareholders.

FEDERAL INCOME TAX INFORMATION (UNAUDITED)

The Fund is required by the Internal Revenue Code to advise shareholders within
60 days of the Fund's fiscal year end (October 31, 2007) as to the federal tax
status of dividends paid by the Fund during such fiscal year. Accordingly, the
Fund paid long-term capital gain distributions of $71,701,490.

The dividends paid by the Fund during the fiscal year ended October 31, 2007
should be multiplied by 58.8% to arrive at the amount eligible for qualified
dividend income, 18.7% for qualified interest income and 62.0% for the corporate
dividends received deduction.

In January 2008, shareholders will receive an IRS Form 1099-DIV or substitute
Form 1099 the federal tax status of the distributions received by shareholders
in calendar year 2007. The amounts that will be reported on such 1099-DIV will
be the amounts you are to use on your federal income tax return and will differ
from the amounts which we must report for the Fund's fiscal year ended October
31, 2007.

ITEM 2. CODE OF ETHICS.

As of the end of the period covered by this report, the Registrant has adopted a
code of ethics (the "Code") that applies to the Registrant's principal executive
officer ("PEO") and principal financial officer ("PFO"). The Code was not
amended during the period covered by the report. A copy of the Code is filed
herewith. The Registrant did not grant any waivers, including implicit waivers,
from any provisions of the Code to the PEO or PFO during the period covered by
this report.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees has determined that the Registrant has two audit committee
financial experts serving on its Audit Committee. The Audit Committee financial
experts are Alan R. Latshaw and Roman L. Weil. Messrs. Latshaw and Weil are
"independent" within the meaning of that term under the Investment Company Act
of 1940.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees

The aggregate fees billed for the fiscal year ended October 31, 2007 for
professional services rendered by KPMG LLP ("KPMG") for the audit of the
Registrant's annual financial statements or services that are normally provided
by KPMG in connection with statutory and regulatory filings or engagements for
that fiscal year were $747,000.

The aggregate fees billed for the fiscal year ended October 31, 2006 for
professional services rendered by KPMG for the audit of the Registrant's annual
financial statements or services that are normally provided by KPMG in
connection with statutory and regulatory filings or engagements for that fiscal
year were $812,750.

(b) Audit Related Fees

The aggregate fees billed for assurance and related services by KPMG that are
reasonably related to the performance of the audit of the Registrant's financial
statements and are not reported under paragraph (a) of this Item were: (i)
$0 for the fiscal year ended October 31, 2007, and (ii) $0 for the fiscal
year ended October 31, 2006. These audit-related services include review of
financial highlights for Registrant's registration statements and issuance of
consents to use of the auditor's reports.

(c) Tax Fees



The aggregate fees billed for professional services rendered by KPMG for tax
compliance, tax advice, and tax planning were: (i) $70,700 during the fiscal
year ended October 31, 2007, and (ii) $90,100 during the fiscal year ended
October 31, 2006. These services primarily included preparation of federal,
state and local income tax returns and excise tax returns, as well as services
relating to excise tax distribution requirements.

(d) All Other Fees

The aggregate fees billed for products and services provided by KPMG, other than
the services reported in paragraphs (a) through (c) of this Item were: (i)
$0 during the fiscal year ended October 31, 2007, and (ii) $0 during the
fiscal year ended October 31, 2006.

(e) Pre-Approval Policies and Procedures

     (1) The Registrant's Audit and Compliance Committee has adopted
     pre-approval policies and procedures (the "Procedures") to govern the
     Committee's pre-approval of (i) all audit services and permissible
     non-audit services to be provided to the Registrant by its independent
     accountant, and (ii) all permissible non-audit services to be provided by
     such independent accountant to the Registrant's investment adviser and to
     any entity controlling, controlled by or under common control with the
     investment adviser that provides ongoing services to the Registrant
     (collectively, the "Service Affiliates") if the services directly relate to
     the Registrant's operations and financial reporting. In accordance with the
     Procedures, the Audit and Compliance Committee is responsible for the
     engagement of the independent accountant to certify the Registrant's
     financial statements for each fiscal year. With respect to the pre-approval
     of non-audit services provided to the Registrant and its Service
     Affiliates, the Procedures provide that the Audit and Compliance Committee
     may annually pre-approve a list of the types of services that may be
     provided to the Registrant or its Service Affiliates, or the Audit and
     Compliance Committee may pre-approve such services on a project-by-project
     basis as they arise. Unless a type of service has received general
     pre-approval, it will require specific pre-approval by the Audit and
     Compliance Committee if it is to be provided by the independent accountant.
     The Procedures also permit the Audit and Compliance Committee to delegate
     authority to one or more of its members to pre-approve any proposed
     non-audit services that have not been previously pre-approved by the Audit
     and Compliance Committee, subject to the ratification by the full Audit and
     Compliance Committee no later than its next scheduled meeting. To date, the
     Audit and Compliance Committee has not delegated such authority.

     (2) With respect to the services described in paragraphs (b) through (d) of
     this Item 4, no amount was approved by the Audit and Compliance Committee
     pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) There were no hours expended on KPMG's engagement to audit the Registrant's
financial statements for the most recent fiscal year attributable to work
performed by persons other than KPMG's full-time, permanent employees.



(g) All non-audit fees billed by KPMG for services rendered to the Registrant
for the fiscal years ended October 31, 2007 and October 31, 2006 are disclosed
in 4(b)-(d) above.

The aggregate non-audit fees billed by KPMG for services rendered to the
Registrant's investment adviser (not including any sub-adviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the Registrant were
approximately: (i) $32,750 for the fiscal year ended October 31, 2007, and
(ii) $25,000 for the fiscal year ended October 31, 2006.

(h) The Registrant's Audit and Compliance Committee has determined that the
non-audit services rendered by KPMG for the fiscal year ended October 31, 2007
to the Registrant's investment adviser and any entity controlling, controlled
by, or under common control with the Registrant's investment adviser that
provides ongoing services to the Registrant that were not required to be
pre-approved by the Audit and Compliance Committee because they did not relate
directly to the operations and financial reporting of the registrant were
compatible with maintaining the respective independence of KPMG during the
relevant time period.

Since the Registrant's last response to this Item, there have been no material
changes to the procedures by which shareholders may recommend nominees to the

ITEM 11. CONTROLS AND PROCEDURES.

(a) Based on an evaluation of the Registrant's Disclosure Controls and
Procedures (as defined in Rule 30a-3(c) under the Investment Company Act of
1940) (the "Disclosure Controls"), as of a date within 90 days prior to the
filing date (the "Filing Date") of this Form N-CSR (the "Report"), the
Registrant's principal executive officer and principal financial officer have
concluded that the Disclosure Controls are reasonably designed to ensure that
information required to be disclosed by the Registrant in the Report is

ensuring that information required to be disclosed in the Report is accumulated
and communicated to the Registrant's management, including the Registrant's
principal executive officer and principal financial officer, as appropriate to
allow timely decisions regarding required disclosure.

(b) There were no changes in the Registrant's internal control over financial
reporting (as defined in Rule 30a-3(d)) under the Investment Company Act of 1940
that occurred during the second fiscal quarter of the period covered by this
report that has materially affected, or is reasonably likely to materially
affect, the Registrant's internal control over financial reporting.
